1.13.3 INTER-REPEATER DATA
COMMUNICATION
1.13 REPEATER INFORMATION
Data communication between VIKING VX and
LTR repeaters at a site is via a high-speed data bus.
This bus cable is installed in a daisy-chain manner
between repeaters. If both VIKING VX and LTR
repeaters are located at a site, 20 repeaters can be
interconnected. Refer to Section 2.10 for information
on connecting the data bus.
1.13.1 INTRODUCTION
NOTE: The Viking VX does not require a separate LTR
logic drawer.
The repeater model used in an LTR system is
determined by frequency range. 800 MHz systems use
the VIKING VX (-232/-234) or LTR 8000s, UHF use
1010s, and VHF use 1100s. Repeaters operate on a
single frequency (one repeater is required for each
channel). The MPC in each repeater performs all
control and signaling functions on that channel. Information is exchanged between repeaters via a highspeed data bus (modular cable). No system controller
is required.
1.13.4 MOBILE TRANSCEIVERS
The mobile and handheld transceivers used in an
LTR system must be compatible with the type of
signaling in use and also the frequency range.
1.14 REPEATER DATA BUS SIGNALING
1.14.1 GENERAL
Optional accessories, such as the Telephone Interconnect Card (TIC) can be installed in the repeater and
the ID Validator drawer can be installed in the repeater
rack. Refer to Johnson LTR ID Validator Manual, Part
No. 001-4408-501 and Johnson Telephone Interconnect Card Manual, Part No. 004-2000-370 for detailed
information.
A single-line serial data bus interconnects the
logic units of all the LTR repeaters at the site. The first
repeater powered on generates the synchronization
pulse that is used by all other repeaters to determine
their time slot on the data bus. If all repeaters are
powered on at the same time, the lowest numbered
repeater generates the synchronization pulse. There are
21 slots with 1-20 used for repeater reporting and 21
used by the ID Validator (see Section 1.14.3). The time
slot used by a repeater is determined by the number
assigned to that repeater by the programming in the
MPC. Repeater 1 uses time slot 1, repeater 5 uses time
slot 5, and so on. The data rate on the repeater data bus
is 18,750 bits per second.
1.13.2 HOME REPEATERS
All mobiles have one of the site repeaters
assigned as its “Home” repeater. This is the repeater
from which it receives most of its control information.
When a mobile is not placing or receiving a call, it is
always monitoring its Home repeater to determine
which channel is free and if it is being called by
another mobile.
In its time slot, each repeater places information
on the data bus indicating its status. If a repeater is not
busy, only start bits appear in its slot. If a repeater is
busy, it places in its slot the Home repeater and ID
code of the mobile receiving the call on that repeater.
If a repeater number is unassigned, nothing appears in
that time slot.
The Home repeater is always used to make a call
unless it is busy. When the Home repeater is busy, any
other repeater in the site may then be used. Up to 250
ID codes are assigned to each repeater. An ID code
and Home repeater number are the “address” of the
mobiles in the system. Therefore, up to 1250 separate
addresses can be assigned in a 5-repeater system and
up to 5000 can be assigned in a 20-repeater system. An
ID code may be assigned to an individual mobile or a
group of mobiles as required.
1.14.2 MOBILE DATA MESSAGE ORDER
Each repeater monitors all the time slots on the
repeater data bus. If it detects its number in another
time slot, it begins transmitting an additional data
message to its mobiles. This message tells mobiles
1-7
Part No. 001-2008-204
combinations possible with a 20-channel system. Each
combination is programmed as either valid or invalid.
Information in the twenty time slots on the repeater
data bus is monitored. If an invalid home repeater/ID
code combination is detected, the ID Validator places
in time slot 21 the number of the repeater being used
by the invalid mobile and also the ID code. When a
repeater detects its number in slot 21, it transmits the
turn-off code (31) to the mobile receiving the call.
That mobile then squelches and resumes monitoring
its home channel. This effectively disables the invalid
mobile because it cannot talk to anyone. When the
turn-off code is sent, the repeater places “21” in the
repeater position of its time slot to indicate to the ID
validator that turn-off has occurred.
programmed to detect that ID code to go to that
repeater to receive a call. This additional message
continues for as long as the mobile is transmitting on
the other repeater.
The sequence of data messages transmitted on a
home repeater is as follows: Every third message is to
the mobile currently receiving a call on that repeater.
Then alternating between these messages are messages
to its mobiles that have been trunked to other
repeaters. For example, assume that five different
mobiles on a five-repeater system are making calls. If
all have Repeater 1 as their home channel (not very
likely in actual practice), the data message order on
Repeater 1 is as follows: 1 2 3 1 4 5 1 2 3 and so on.
1.14.3 ID VALIDATOR OPERATION
If the ID Validator is used, it is programmed with
the status of up to all 5000 home repeater/ID code

INSTALLATION
SECTION 2 INSTALLATION
2.1 INTRODUCTION
NOTE: If the Repeater is installed in an area that exceeds these environmental conditions, the site should
be equipped with air filters to remove dust and dirt that
could cause the equipment to overheat. The cabinets
and filters should be placed on a maintenance schedule.
Information in this section tells how to set up the
repeater for operation in an LTR system. It is assumed
that the repeater has been previously aligned at the
factory or as described in the alignment procedure in
Section 6.
When the repeaters are installed in an environment that contains small airborne particles, e.g. grain
dust or salt fog, the repeater cabinets need to be
sealed. A heat exchanger, i.e. air conditioner, is then
required to cool the cabinets. The air conditioners
must be suited for the environment. Each low power
repeater (75W) requires >1200 BTU/hr dissipation to
maintain exterior cabinet temperature. Each high
power (160W or 175W) requires >2100 BTU/hr dissipation to maintain exterior cabinet temperature.
Even though each repeater is thoroughly aligned
and tested at the factory, it is good practice to check
performance before it is placed in service. This
ensures that no damage occurred during shipment and
that the repeater is otherwise operating properly.
Performance testing is described in Sections 6.2, 6.3,
6.4, and 6.5.
2.2 SITE PREPARATION AND ANTENNA
INSTALLATION
Site preparation and antenna installation are not
within the scope of this manual. Basic installation
requirements are discussed in the “Dealer Guide To
Site Preparation”, Part No. 004-8000-100. Factory
installation is also available. Contact your EFJohnson
representative for more information.
2.4 VENTILATION
The RF modules and the power supply are
equipped with fans, controlled by thermostats, that
force air through the equipment for cooling. The air
flow is from the front to the back of the equipment.
This permits the Repeaters to be stacked or rack
mounted (see Figure 2-4). There are a few considerations when installing Repeaters to provide adequate
air circulation.
2.3 ENVIRONMENT
The following conditions should be considered
when selecting a site for the Repeater.
1. The Repeaters should be mounted with a minimum
of 6 inches clearance between the front or back of
the cabinet for air flow. The power supply requires
a minimum of 18 inches at the back of the Repeater
for removal.
Operating Temperature
–30°C to +60°C (–22°F to +140°F).
Humidity.
NOTE: Repeaters should not touch. Leave a minimum
of one empty screw hole (approximately 1/2”) between
repeaters vertically especially for bottom ventilation
slots in high power repeaters.
Less than 95% relative humidity at 50°C.
Air Quality.
For equipment operating in a controlled environment with the Repeaters rack mounted, the airborne
particles must not exceed 30 µg/m3.
For equipment operating in an uncontrolled environment with the Repeaters rack mounted, the
airborne particles must not exceed 100 µg/m3.
2-1
•
Cabinet enclosures must provide air vents for
adequate air circulation.
•
Temperature and humidity must be considered
when several Repeaters are installed at a site. This
might require air conditioning the site.

The AC power source to the Johnson Viking VX
Repeater can be 120V AC or 240V AC. Nothing need
be done to the power supply for 240V AC operation.
However, a 240V AC outlet requires that the 120V
AC power plug be replaced. A locking AC power cord
is provided for the supply.

FAULT
The 120V AC cord is a standard 3-wire grounded
cord used with a standard AC wall outlet. The outlet
must be capable of supplying a maximum of 328W (232) or 680W (-234). With the nominal 120V AC
input, the source must supply 3A for each 75W
repeater or 6A for each 175W repeater and should be
protected by a circuit breaker. It is recommended that
all of the repeaters in a rack should not be on the same
breaker in order to provide one operational repeater in
the event a breaker trips. An AC surge protector is
recommended for all equipment.

Each Repeater requires an outlet, so for a 5channel system, a minimum of 5 outlets is required.
An additional three outlets should be added for test
equipment. The outlets must be within 3 feet of each
Repeater cabinet. Future system expansion should be
considered when electrical work is being planned for
the initial system.

Figure 2-2 Temperature Sensor Cable
The Viking VX Repeater power supply can be
equipped with an optional 24V DC back-up in the
event of AC power failure. Since the transmitter will
remain on full power, if desired, the DC power source
must have a current capability of about 15A per 75W
repeater (25A per 175W repeater) or 75A for 5-75W
repeaters (125A for 5-175W repeaters). The multicoupler requires another 0.5A for a total system requirement at 24V DC of 75.5A for 75W repeaters (125.5A
for 175W repeaters).
2.7 800W POWER SUPPLY
The power supply has four voltage output levels
(see Table 2-1). Each voltage is set to ±1% at +25°C
(+77°F). The output of this supply is capable or
running any 2000 series repeater.
Each output is overload protected such that the
power supply current limits and automatically resets
when the overload is removed (see Table 2-1).
2.6 BATTERY BACKUP
Each output is over voltage protected such that
the power supply shuts down when an over voltage
condition exists, usually when a component in the
supply has failed (see Table 2-2). The power supply
must be manually reset by toggling the Enable Line or
removing AC power for more than 10 seconds.
If the power supply is equipped with battery
backup, screw lugs are provided on the front of the
power supply for battery connections (see Figure 2-1).
A switch is provided for charging the battery or can be
off if a separate battery charger is used. A battery

INSTALLATION
Secondary protection (other than grounding)
provides the equipment protection against line transients that result from lightning. There are two types of
secondary protection, RF and Telephone Line. Use the
same wire sizes as specified for coaxial cables for any
ground connections required by the secondary protectors.
The operating temperature range is -30°C to
+60°C (-22°F to +140°F), i.e. the same as the repeater.
The fan is thermostatically controlled by the internal
temperature. When the internal heatsink temperature
reaches +45°C (113°F) the fan turns on. When the
heatsink temperature drops below +35°C (95°F) the
fan turns off. If the internal heatsink temperature
reaches +90°C (+194°F) the power supply turns off
until the heatsink temperature drops below +85°C
(+185°F). The over-temperature shutdown and restart
are automatic.
•
RF
An RF protector keeps any lightning strike to the
antenna feed line or tower from damaging the
Repeaters. Install this protection in-line with the
combiner and antenna feed line.
2.8 GROUNDING
CAUTION
RF protectors are selected by calculating the
maximum instantaneous voltage at the output of the
combiner. Do this by using the following equation.
Proper site grounding and lightning protection are
very important to prevent permanent damage to the
repeater.
Vp = 1.414 ( X ) ( P ( 50 ) )
where:
VP = Voltage at the output of the combiner.
P = repeater output in watts
As in any fixed radio installation, measures
should be taken to reduce the possibility of lightning
damage to the Viking VX equipment. Proper
grounding eliminates shock hazard, protects against
electromagnetic interference (EMI) and lightning.

Ground each piece of equipment separately. Do
not ground one piece of equipment by connecting it to
another grounded piece of equipment.
A good DC ground must be found or created at
the site. Rooftop site grounds can be researched
through the building management or architects. Tower
site grounds must be made with grounding rods. The
many techniques for providing adequate grounds for
towers and poles and for installing building ground
bus lines are beyond the scope of this manual. Refer to
National Electrical Code article 250 “Grounding Techniques,” article 800 “Communications Systems” and
follow local codes.

Telephone Line
The ground bus should be routed to the floor area
within 5 feet of the system with a runner of 6 AWG or
larger solid copper wire or 8 AWG stranded copper
wire.
There are four types of protection suppressors for
telephone lines; Gas Tube, Silicon Avalanche Diode,
Metal Oxide Varistor and Hybrid.
The outer conductor of each transmission line at
the point where it enters the building should be
grounded using 6 AWG or larger solid copper wire or
8 AWG stranded wire.
The hybrid protector is ideal for EFJohnson
equipment, and is strongly recommended. A hybrid
suppressor combines several forms of protection not
available in just one type of device. For example, a
Part No. 001-2008-204

INSTALLATION
high-speed diode reacts first, clamping a voltage strike
within 10 ns, a heavy duty heat coil reacts next to
reduce the remainder of the current surge, and a highpowered three-element gas tube fires, grounding Tip
and Ring.
Protection Guidelines
Follow these guidelines for grounding and lightning protection. Each Repeater installation site is
different; all of these may not apply.
•
Ensure that ground connections make good metalto-metal contact (grounding rod, grounding tray,
metal conduit) using #6 gauge solid wire or braided
wire straps.
•
With surge protectors, ensure that ground wires go
directly to ground, and not through other equipment.
•
Run the ground wire for RF coax protectors directly
to ground.
•
With coax protectors, ensure maximum instantaneous voltage does not exceed the rated voltage.
•
Do not run ground wires parallel to any other wiring
(e.g. a ground wire parallel to a telephone line),
except other ground wires.
•
Double check all equipment for good ground and
that all connections are clean and secure
.
2.9 UNPACKING AND INSPECTION
EFJohnson ships the Repeater securely crated for
transportation. When the Repeater arrives, ensure the
crates remain upright, especially if storing the crates
temporarily.
When unpacking the Repeater, check for any
visible damage or problems caused by shipping. If
there is obvious damage from shipping mishaps, file
claims with the carrier. If there appears to be any
damage caused before shipping, file a claim with
EFJohnson. Contact Customer Service for assistance
(see Section 1.7).

Adapter Module is installed on the back of the Viking
VX repeater cabinet (see Figures 2-13 and 2-14).
If everything appears undamaged, remove the
Repeater equipment from the crate, using normal
precautions for unpacking.
NOTE: Do not discard the packing materials. If you
must return an item; use the same packing materials
and methods (including static protective bags for circuit cards) to repack the equipment. You are responsible for proper repacking. EFJohnson cannot be
responsible for damage to equipment caused by negligence.
Systems constructed only with LTR Viking VX
repeaters that have Version 202 or later HSDB software (see Section 3.5.4) and do not use VNC cards can
be connected directly to the HSDB from the RJ-11
jack on the back of the repeater.
2.10.1 MPC DATA BUS SWITCH SETTINGS
NOTE: Repeaters should not touch. Leave a minimum
of one empty screw hole (approximately 1/2”) between
repeaters vertically especially for bottom ventilation
slots in high power repeaters.
Switch settings on the MPC for the two types of
installations require S2 and S3 sections to be switched
as indicated in Figure 2-6.
NOTE: Each repeater should be grounded separately
by connecting a ground bus from the ground lug on the
back side of the RF module to the ground bar on the
rack (see Figure 2-8).

SECTION 3 SOFTWARE DESCRIPTION
3.1 GENERAL
3.1.3 COMPUTER DESCRIPTION
3.1.1 INTRODUCTION
The programming software is designed to run on
an IBM PC or compatible computer that meet the
following minimum requirements.
The EFJohnson Viking VX Repeater Programming Software, Part No. 023-9998-297, is supplied on
3.5 inch disk. This software uses an IBM® or compatible personal computer capable or running MS-DOS
(it is not a Windows program). The programming data
is stored in an EEPROM memory device on the Main
Processor Card (MPC). The computer is connected to
the repeater MPC using a special interconnect cable
(see Section 3.1.3).
•
•
•
•
•
One 3.5" high density disk drive
640K of memory
MS-DOS version 2.0 or higher
One serial port
Monochrome or color monitor and video card
Although the program uses color to highlight
certain areas on the screen, a monochrome (black and
white) monitor or LCD laptop also provide satisfactory operation.
3.1.2 PROGRAMMING AND ALIGNMENT
SOFTWARE
An available serial port is required to connect the
repeater to the computer. This port is standard with
most computers. A programming cable similar to that
shown below is required to connect the serial port to
the MPC of the repeater. A DB-9 F to 8-pin modular
adapter connects to the serial port, and an interconnect
cable with an 8-pin modular connector on each end
connects from this adapter to the MPC. These components are included in Programming Cable Kit, Part No.
023-2000-195.
The Viking VX software displays a menu bar (see
Figure 3-2) that is used to select functions which
program, tune, and test the repeater as follows:
Programming Functions
The main programming menu functions are File,
Edit, and Transfer. These functions are used to create,
edit, transfer, and receive repeater and channel parameters. Files are created that store these parameters.
Refer to Section 5?? for more information on repeater
programming.
TO MPC
Alignment and Test Functions
The Test menu functions are used to perform the
repeater alignment described in Section 6. As shown
in the following screen, there are separate functions
for the PA (see Section 6.5), Receiver (see Section
6.2), Exciter (see Section 6.3) and overall Full
Repeater (see Section 6.6) including the MAC card.

3.1.4 EEPROM DATA STORAGE
The data programmed into the MPC is stored by
an EEPROM memory. Since this type of device is
nonvolatile, data is stored indefinitely without the
need for a constant power supply. A repeater can be

without affecting programming. Since EEPROM
memory is also reprogrammable, a new device is not
needed if programming is changed.

3.1.6 COMMAND LINE OPTIONS
3.1.5 GETTING STARTED
The following options can be run from the
command line if desired when starting the program.
Most of these options can also be selected in the Utilities menu and the selected configuration is automatically reloaded the next time the program is run.
NOTE: To use this program, you should have a basic
understanding MS-DOS® functions.
Copy all the files on the programming disk into a
folder on the hard drive. The other files included on
the disk must be in the same folder as this file. The
program can also be run directly from the master disk
if desired. However, in this case, it is recommended
that a copy is used and the master be stored in a safe
place. There is no installation program that automatically installs the program on the computer.
•
To show all options available from the command
line type: /h or /?. Either ’/’ or ’-’ can be used. For
example: 2000pgmr /h
The options can be entered in any order.
For example: 2000pgmr /d /b /c
The program is run by simply executing the
“2000pgmr.exe” file. This is done from the DOS
prompt (usually C:\) by typing “2000pgmr” (without
quotes) and pressing Enter.
•
1. When running the compiled (.EXE) version, type /
c2 on the command line after the program name.
For example: 2000pgmr /c2 or -c2
2. Select COM port from Utilities heading.
•
The programming software utilizes color which
may make LCD-type displays hard to read because the
contrast is poor. To improve contrast, a monochrome
mode can be selected in the Utilities > Display Mode
menu.
BAUD RATE
The software defaults to 9600 baud, however this
rate can be changed. To do this from the command
line, type /bxxxx (xxxx = baud rate).
For example: 2000pgmr /b or -b
The following are the files included on the
programming disk and the size of each:
Part No. 001-2008-204
COM Port
The Johnson programming software defaults to
serial port COM1. However, if this port is already in
use, the software can be reconfigured to use serial port
COM2. To do this, use one of the following methods:
As previously described, menus are used for
selecting the desired functions. The available menus
are listed in the bar at the top of the screen (see Figure
3-2). Move the cursor with the arrow keys to highlight
the menu name. Press Enter to view the menu and the
arrow keys to scroll through the menu. Call up the
highlighted selection by pressing Enter. When applicable, pressing the spacebar displays the available
selections.

If you have a single floppy drive and no hard disk
drive, you need to create programming disks. The
reason for this is that there is not adequate space on the
backup disk(s) for storing radio files. If your
computer has dual floppy disk drives, the backup disk
can be placed in one drive and then the radio files
stored on a disk in the second drive.

used. Normally these screens are not available without
a repeater connected. To do this from the command
line, type: /d or -d.
For example: 2000pgmr /d
3.1.7 HELP F1
To make a programming disk, format a blank disk
using FORMAT B: or FORMAT B: /S (use “/S” if it
must be a bootable disk). Then copy the required
program file or files to the programming disk. To do
this, type COPY A:(filename.ext) B:(filename.ext).
For example, to copy the file 2000pgm2.exe from
drive A to drive B, type the following. This procedure
works for either single or dual drive computers.
Help screens are available for most parameters
and options in this program. Whenever a parameter or
options clarification is needed, press F1 and if a help
screen is available it will pop-up on the screen. Press
Escape <ESC> to exit the pop-up screen.
3.1.8 MINIMUM FREE MEMORY REQUIRED
COPY A:2000pgm2.exe B:2000pgm2.exe
Approximately 525K of free conventional
memory is required to run this program (use the
CHKSK or MEM command to display the amount of
free memory). If you have at least 640K of memory
and not enough is available, there may be other
programs that are also being loaded into conventional
memory. These programs can be moved or disabled to
make more space available.
3.2 FILE MENU
3.1.9 DOS FUNCTIONS
When you receive the programming software,
make a backup copy and store the master in a safe

3.5.3 RF DATA
High Speed Data Bus (HSDB) connects all
repeaters at a site and continually sends updates on the
status of each repeater. This information screen provides a list of all repeaters at the site (1 to 20). If a
repeater is not sending data, IDLE is next to the
repeater number. The data sent by the repeater is used
to determine the Home, GID and UID of destination
(mobile) users to receive the call placed by the originator.
The A/D Monitor Screen shows the state of various lines monitored by the A to D converter in the
IAC. The normal values for each line are as follows.
The Home column refers to the Home repeater
number of the originator. Therefore, the Repeater
number and the Home number may not be the same
number. The UID is the Unique ID used to identify the
originator of special calls. The GID column refers to
the Group ID of the talk group of the originator
(236=UID Call, 237 Telco call). The GoTo column
shows the repeater channel all destination users switch
to so they receive the call.

CIRCUIT DESCRIPTION
SECTION 5 CIRCUIT DESCRIPTION
5.1 RECEIVER
Additional filtering of the receive signal is provided
by 3-pole helical filter L204-L206. A section of
microstrip on the collector of Q201 and C205/C207
match the impedance from Q201 to 3-pole helical
filter L204-L206.
5.1.1 INTRODUCTION
The receiver is a double conversion type with
intermediate frequencies of 52.95 MHz and 450 kHz.
The first injection frequency is phase locked to a
temperature compensated crystal oscillator (TCXO)
with a frequency stability of ±1.0 PPM from –30° to
+60° C (–22° to +140° F). Two 3-pole bandpass filters
in the front-end reject signals outside the receive band.
Two 4-pole crystal filters and one 6-pole ceramic filter
establish receiver selectivity (see block diagram
Figure 5-1).
5.1.4 FIRST MIXER, CRYSTAL FILTER
5.1.2 REGULATED VOLTAGE SUPPLIES
First mixer U201 mixes the receive frequency
with the first injection frequency to produce the 52.95
MHz first IF. Since low-side injection is used, the
injection frequency is 52.95 MHz below the receive
frequency. Matching between filter L204-L206 and
the mixer is provided by L228, C208 and C372. The
output of U201 is matched to Z201 at 52.95 MHz by
L207, C209 and C267.
The +15V DC power source is supplied by the
repeater power supply. The +15V supply enters the
receiver on J201, pin 1. U206 provides the +12V DC
receive voltage to the RF and IF amplifiers. U210
supplies +12V DC to the first injection amplifiers.
U207 supplies +12V DC to the remaining +12V DC
circuits. U208 supplies +6V DC to the remaining
circuits.
Z201 and Z202 form a two-section, four-pole
filter with a center frequency of 52.95 MHz and a –3
dB bandwidth of 15 kHz. This filter attenuates adjacent channels and other signals close to the receive
frequency. The filter sections are a matched pair and
the dot on the case indicates which leads connect
together. Matching with Q202 is provided by C210,
L209 and C270.
5.1.5 IF AMPLIFIER, CRYSTAL FILTER
5.1.3 HELICAL FILTER, RF AMPLIFIER
Q202 amplifies the 52.95 MHz IF signal to
recover filter and mixer losses and improve receiver
sensitivity. Biasing for Q202 is provided by R208/
R209/R211/R313 and C211/C212/C213 provide RF
bypass. The output of Q202 is matched to crystal filter
Z203 at 52.95 MHz by C214, C293 and L211.
The receive signal enters the receiver on coaxial
connector A201. A helical filter consisting of L201,
L202 and L203 is a three-pole bandpass filter tuned to
pass only a narrow band of frequencies (806-824
MHz) to the receiver. This filter also attenuates the
image and other unwanted frequencies.
Z203 and Z204 form a two-section, four-pole
filter with a center frequency of 52.95 MHz and a –3
dB bandwidth of 15 kHz. This filter establishes the
selectivity of the receiver by further filtering the 52.95
MHz IF. The filter sections are a matched pair and the
dot on the case indicates which leads connect together.
Matching with U202 is provided by C215, C216,
C301, L225 and R322.
Impedance matching between the helical filter
and RF amplifier Q201 is provided by C201, C202
and a section of microstrip. Q201 amplifies the
receive signal to recover filter losses and increases
receiver sensitivity. Biasing for Q201 is provided by
R201/R202/R203/R204 and C204 provides RF
bypass. A 1.8 dB attenuator follows amplifier Q201.

5.1.6 SECOND MIXER/DETECTOR
Biasing of Q205 is provided by R228, R227 and
R229. RF choke L214 blocks the flow of RF through
R229. An AC voltage divider formed by C236/C235
matches Q205 to the high pass filter. The third
harmonic of the TCXO frequency is then used to drive
the OSC B input at 52.5 MHz. L215, C237 and L216
for a high pass filter to attenuate frequencies below
52.95 MHz. C222 and C238 match the output of the
filter to U202.
As shown in Figure 5-2, U202 contains second
oscillator, second mixer, limiter, detector and RSSI
circuitry. The 52.95 MHz IF signal is mixed with a
52.5 MHz signal produced by TCXO Y201 and tripler
Q205. The 17.5 MHz (±1 PPM) output of Y201 is fed
through C231 to tripler Q205. The tripler passes the
third harmonic at 52.5 MHz to the oscillator input of
U202.
OSC B 1
The 450 kHz second IF is then fed to ceramic
filter Z205, then into the IF amplifier. The center
frequency of Z205 is 450 kHz with a bandwidth of 15
kHz used to attenuate wideband noise. The limiter
amplifies the 450 kHz signal 92 dB which removes
any amplitude fluctuations.

From the limiter the signal is fed to the quadrature detector. An external phase-shift network
connected to U202, pin 8, shifts the phase of one of
the detector inputs 90° at 450 kHz (the other inputs are
unshifted in phase). When modulation occurs, the
frequency of the IF signal changes at an audio rate as
does the phase of the shifted signal. The detector,
which has no output with a 90° phase shift, converts
the phase shift into an audio signal. Z213 is adjusted
to provide maximum undistorted output from the
detector. The audio signal is then fed out on U202,
pin 9.

CIRCUIT DESCRIPTION

change and transistor current remains constant. R803
decouples the VCO output from AC ground. L803 is
an RF choke and C807, C808, C810 and C811 provide
RF bypass.
U203B amplifies the detected audio and data
signal. R280/R263 set the gain of the amplifier and
R256/R262/R284 provide a DC reference level. C220
bypasses the 450 kHz IF signal and C240 bypasses
other frequencies. The output signal is adjusted by
R264 and fed to J201, pin 9.
5.1.11 BUFFER
A cascode amplifier formed by Q208/Q209
provides amplification and isolation between the VCO
and Synthesizer. A cascode amplifier is used because
it provides high gain, high isolation and consumes
only a small amount of power. The input signal to this
amplifier is coupled from the VCO RF output on pin
4. DC blocking and coupling to the VCO is provided
by C268 and to the buffer by C261. Bias for the amplifier is provided by R275, R279, R278 and R277. Q209
is a common-emitter amplifier and Q208 is a commonbase with C260 providing RF bypass. L219 provides
some filtering of the cascode output. R273 lowers the
Q of L219. The output of the amplifier is coupled by
C309 to U209, pin 11.
5.1.8 RSSI AMPLIFIER
U202, pin 13 is an output from an internal RSSI
(receive signal strength indicator) circuit which
provides a current proportional to the strength of the
450 kHz IF signal. The RSSI output is buffered
through U203A and the level is adjusted by R261. The
DC output signal is then fed to J201, pin 7.
5.1.9 VCO
The Voltage-Controlled Oscillator (VCO) is
formed by Q802 circuitry and a resonator consisting of
L220 in the Receiver. The adjusting screw in L220
tunes the tank circuit to the desired frequency range.
The VCO oscillates in a frequency range from 753771 MHz. Biasing of Q802 is provided by R805, R806
and R807. AC voltage divider C812 and C813 initiates
and maintains oscillation. C803 couples Q802 to L220
that provides the shunt inductance of the tank circuit.
The shunt capacitance of the tank circuit is made
primarily by C804 in series with CR802.
5.1.12 SYNTHESIZER
The synthesizer inputs/outputs are shown in
Figure 5-3. The synthesizer output signal is the
receiver first injection frequency. This signal is
produced by a VCO (voltage-controller oscillator).
The frequency of this oscillator is controlled by a DC
voltage. This DC voltage is generated by integrating
the pulses from the phase detector in synthesizer chip
U209. This integration is performed by the synthesizer
loop filter which is made up of C805, C806 and R804
in the VCO circuitry.
The VCO frequency is controlled in part by DC
voltage across varactor diode CR802. As voltage
across a reverse-biased varactor diode increases, its
capacitance decreases. Therefore, VCO frequency
increases as the control voltage increases. The control
line is RF isolated from tank circuit by choke L804.
The amount of frequency change produced by CR802
is controlled by series capacitor C804.
5.1.10 ACTIVE FILTER
Frequencies are selected by programming
counters in U209 to divide by a certain number. This
programming is provided through J201, pins 12, 18
and 20. The frequency stability of the synthesizer is
established by the ±1.0 PPM stability of TCXO Y201.
The output of this oscillator is stable from 30°C to
+60°C (–22°F to +140°F).
Q801 functions as a capacitance multiplier to
provide filtering of the 12V supply to Q802. R801 and
R802 provide transistor bias, and C809 provides the
capacitance that is effectively multiplied by the gain of
Q801. If a noise pulse or other voltage change appears
on the collector, the base voltage does not change
because of C809. Therefore, the base current does not
The VCO frequency of A006 is controlled by a
DC voltage produced by integrating the phase detector
output pulses of U209 The phase detector senses the
phase and frequency of the two input signals (fV and
fR) and causes the VCO control voltage to increase or
decrease if they are not the same. When the frequencies are the same the VCO is “locked” on frequency.

One input signal to the phase detector in U209 is
the reference frequency (fR). This is the 17.5 MHz
TCXO frequency divided by the R (reference) counter
to the channel spacing or 12.5 kHz.
Interface Alarm Card (IAC) and fed into the synthesizer on J201, pin 20 to Data input port U209, pin 19.
Data is loaded into U209 serially on the Data
input port U209, pin 19. Data is clocked into the shift
registers a bit at a time by a low to high transition on
the Clock input port U209, pin 18. The Clock pulses
come from the MPC via the IAC to J201, pin 18.
The other input to the phase detector in U209 is
from the VCO frequency divided down by the “N”
counter and prescaler in synthesizer U209 to 12.5 kHz.
The “N” counter is programmed through the synthesizer data line on J201, pin 20. U209 is programmed
so that the phase detector input (fV) is identical to the
reference frequency (fR) (12.5 kHz) when the VCO is
locked on the correct frequency.
As previously stated, the counter divide numbers
are chosen so that when the VCO is operating on the
correct frequency, the VCO-derived input to the phase
detector (fV) is the same frequency as the TCXOderived input (fR) which is 12.5 kHz.
The synthesizer contains the R (reference), N,
and A counters, phase and lock detectors and counter
programming circuitry. Frequencies are selected by
programming the three counters in U209 to divide by
assigned numbers. The programming of these counters
is performed by circuitry in the Main Processor Card
(MPC), which is buffered and latched through the

The fR input is produced by dividing the 17.5
MHz TCXO frequency by 1400. This division is done
by the “R” counter in U209. The counter always
divides by 1400 regardless of the channel number.
This produces a reference frequency (fR) of 12.5 kHz.
Since the VCO is on frequency (receive frequency

minus 52.95 MHz) and no multiplication is used, the
channel frequencies change in 12.5 kHz steps and the
reference frequency (fR) is 12.5 kHz for all channels
selected by this receiver.
A cascode amplifier formed by Q210 and Q211
provides amplification and also isolation between the
TCXO and Synthesizer U209. A cascode amplifier is
used because it provides high reverse isolation. The
input signal to this amplifier is from TCXO Y201.
C254 provides DC blocking. Bias for the amplifier is
provided by R312, R248, R249, R251 and R250. L218
is an RF choke. RF bypass is provided by C251, C252
and C253. The output of Q210/Q211 is coupled to
U209 by C307.
The fV input is produced by dividing the VCO
frequency using the prescaler and N counter in U209.
The prescaler divides by 64 or 65. The divide number
of the prescaler is controlled by the N and A counters
in U209.
The N and A counters function as follows: both
the N and A counters begin counting down from their
programmed number. When the A counter reaches
zero, it halts until the N counter reaches zero. Both
counters then reset and the cycle repeats. The A
counter is always programmed with a smaller number
than the N counter. While the A counter is counting
down, the prescaler divides by 65. Then when the A
counter is halted, the prescaler divides by 64.
5.1.14 LOCK DETECT
When the synthesizer is locked on frequency, the
Lock Detect output on U209, pin 2 is a logic high
voltage with very narrow negative-going pulses. Then
when the synthesizer is unlocked, these pulses become
much wider, the width may vary at a rate determined
by the frequency difference of fV and fR. The lock
detect pulses are applied to J201, pin 14 and sent to the
RF Interface on J103, pin 14 for detection and
sampling in the IAC.
Example: Assume a receive frequency of
813.4875 MHz (channel 300). Since the VCO is 52.95
MHz below the receive frequency it must be 760.5375
MHz for channel 300. To produce this frequency, the
N and A counters are programmed as follows:
N = 950
A = 43
VCO and Receiver RF stages. A cascode amplifier is
used because it provides high reverse isolation. The
input signal to this amplifier is coupled from VCO
A006 by C268. C268 also provides DC blocking. Bias
for the amplifier is provided by R294, R311, R290,
R291 and R292. L222 is an RF choke and R293
lowers the Q of the coil. RF bypass is provided by
C274, C356, C310, C272, C273 and C335. The output
of Q214/Q215 is matched to the Receiver RF stages
by C275, C276 and two sections of microstrip.
NOTE: Section 7.2.5 describes how the N and A
counter numbers can be calculated for other channels.
To determine the overall divide number of the
prescaler and N counter, the number of VCO output
pulses required to produce one N counter output pulse
can be counted. In this example, the prescaler divides
by 65 for 65 x 43 or 2,795 input pulses. It then divides
by 64 for 64 x (950 - 43) or 58,048 input pulses. The
overall divide number K is therefore (58,048 + 2,795)
or 60,843. The VCO frequency of 760.5375 MHz
divided by 60,843 equals 12.5 kHz which is the fR
input to the phase detector. The overall divide number
K can also be determined by the following formula:
5.1.16 RF AMPLIFIERS
U210 provides the +12V source for these amplifiers. RF amplifier Q216 is biased by R296 and R295.
C278 provides RF bypass from the DC line and R297
provides supply voltage isolation. A section of microstrip on the collector acts as an RF inductor. Q216 is
matched to Q217 by C277, C263, C288 and two
sections of microstrip.

CIRCUIT DESCRIPTION
5.2.2 VCO AND TCXO FREQUENCY
MODULATION
RF amplifier/buffer Q217 is similar in design to
Q216. The output of Q217 is matched to the 3 dB
attenuator made up of R285/R286/R287 by two
sections of microstrip and C280 provides DC
blocking. L223/L224 are tuned to the receive
frequency –52.95 MHz and passed to Mixer U201.
This injection frequency is also coupled through C284
to U204A. CR201, R255, R254 provide DC input to
U204A, pin 3. The output of U204A, pin 1 is
connected to J201, pin 13 for a receive injection test
point and connected to the RF Interface Board on
J103, pin 13.
Both the VCO and TCXO are modulated in order
to achieve the required frequency response. If only the
VCO was modulated, the phase detector in U403
would sense the frequency change and increase or
decrease the VCO control voltage to counteract the
change (at the lower audio frequencies inside the
closed loop bandwidth of the synthesizer). If only the
TCXO frequency was modulated, the VCO would not
track the higher audio frequencies (those beyond the
closed loop bandwidth of the synthesizer). However,
by modulating both the VCO and TCXO a flat audio
response is achieved. Potentiometers R425 and R446
balance the modulating signals.
5.2 EXCITER
There are two 3.5V sources on the Exciter board;
one is a reference for the modulation amplifier to the
VCO, the other is for the modulation amplifier to the
TCXO.
5.2.1 VCO
The Voltage-Controlled Oscillator (VCO) is
formed by Q802, associated circuitry and a resonator
consisting of L404 in the Exciter. The screw in L404
in the Exciter tunes the tank circuit to the desired
frequency range. The VCO oscillates in a frequency
range from 851-869 MHz. Biasing of Q802 is
provided by R805, R806 and R807. An AC voltage
divider formed by C812 and C813 initiates and maintains oscillation. C803 couples Q802 to resonator
L404 in the Exciter. Resonator L404 provides the
shunt inductance of the tank circuit. The shunt capacitance of the tank circuit is made primarily of C804 in
series with CR802. RF choke L805 completes the DC
bias path to ground.
The reference voltage on U402B, pin 5 is sent to
buffer U407B, J401, pin 9 to RFIB connector J102,
pin 9. The voltage leaves the RFIB on J101, pin 14 to
J2, pin 27 on the backplane, to the bottom connectors
via pin 7 and finally to the MAC on P100, pin 7.
With reference to the ground on the Exciter, the
3.5V reference stability is maintained by U126B/C/D
on the MAC. The 3.5V DC passes through summing
amplifier U129B and transmit modulation gate U118D
to P100, pin 29 (Tx MOD). P100, pin 29 is connected
to backplane connector J2, pin 8 and RFIB connector
J101, pin 22 to J102, pin 13. The transmit modulation
and 3.5V reference enter the Exciter on J401, pin 13
and is routed to U402B, pin 6. R425 sets the TCXO
modulation level. The modulation signal along with
the 3.5V DC is applied to U402A, pin 2.
The VCO frequency is controlled in part by DC
voltage across varactor diode CR802. As voltage
across a reverse-biased varactor diode increases, its
capacitance decreases. Therefore, VCO frequency
increases as the control voltage increases. The control
line is RF isolated from tank circuit by choke L804.
The amount of frequency change produced by CR802
is controlled by series capacitor C804.
5.2.3 ACTIVE FILTER
Q801 functions as a capacitance multiplier to
provide filtering of the 12V supply to Q802. R801 and
R802 provide transistor bias, and C809 provides
capacitance that is effectively multiplied by the gain of
Q801. If a noise pulse or other quick voltage change
appears on the collector, base voltage does not change
significantly because of C809. Therefore, the base
current does not change and transistor current remains
The frequency is modulated in a similar manner.
The transmit audio/data signal is applied across
varactor diode CR801 to vary the VCO frequency at
an audio rate. C802 in series with CR801 determine
the amount of modulation produced by the audio
signal.

CIRCUIT DESCRIPTION
One input signal to the phase detector in U403 is
the reference frequency (fR). This frequency is the 17.5
MHz TCXO frequency divided by the reference
counter to the channel spacing or 12.5 kHz. The other
input signal (fV) is the VCO frequency divided by the
“N” counter in U403. The counters are programmed
through the synthesizer data line on J401, pin 20. Each
channel is programmed by a divide number so that the
phase detector input is identical to the reference
frequency (fR) when the VCO is locked on the correct
frequency.
constant. R803 decouples the VCO output from AC
ground. L803 is an RF choke and C807, C808, C810
and C811 provide RF bypass.
5.2.4 BUFFER
VCO and synthesizer. A cascode amplifier is used
because it provides high reverse isolation. The input
signal to this amplifier is tapped from the VCO RF
output. DC blocking to the VCO is provided by C441
and to the buffer by C433. Bias for the amplifier is
provided by R451, R453, R454 and R455. Q407 is a
common-emitter amplifier and Q406 is a commonbase with C432 providing RF bypass. L403 decouples
the output from AC ground and R452 lowers the Q of
L403. The amplifier is coupled by C429 and C499 to
U403, pin 11.
Frequencies are selected by programming the
three counters in U403 to divide by assigned numbers.
The programming of these counters is performed by
circuitry in the Main Processor Card (MPC), buffered
and latched through the Interface Alarm Card (IAC)
and fed into the synthesizer on J401, pin 20 to Data
input port U403, pin 19.
5.2.5 SYNTHESIZER
Data is loaded into U403 serially on the Data
input port U403, pin 19 when U403, pin 17 is low.
Data is clocked into the shift registers a bit at a time by
a low to high transition on the Clock input port U403,
pin 18. The Clock pulses come from the MPC via the
IAC to J401, pin 19.
The synthesizer inputs/outputs are shown in
Figure 5-3. The synthesizer output signal is the
transmit frequency. This signal is produced by a VCO
(voltage-controller oscillator) that is frequency
controlled by a DC voltage produced by synthesizer
chip U403. This DC voltage is filtered by a loop filter
made up of C805, C806 and R804 in the VCO
circuitry.
As previously stated, the counter divide numbers
are chosen so that when the VCO is operating on the
correct frequency, the VCO-derived input to the phase
detector (fV) is the same frequency as the TCXOderived input (fR). The fR input is produced by
dividing the 17.5 MHz TCXO frequency by 1187.
This produces a reference frequency (fR) of 12.5 kHz.
Since the VCO is on frequency and no multiplication
is used, the frequencies are changed in 12.5 kHz steps.
The reference frequency is 12.5 kHz for all frequencies selected by this Exciter.
Frequencies are selected by programming
counters in U403 to divide by a certain number. This
programming is provided through J401, pins 12, 19
and 20. The frequency stability of the synthesizer is
established by the ±1.0 PPM stability of TCXO Y401.
This oscillator is stable from –30°C to +60°C (–22°F
to +140°F).
The VCO frequency of A007 is controlled by a
DC voltage produced by the phase detector in U403.
The phase detector senses the phase and frequency of
the two input signals and causes the VCO control
voltage to increase or decrease if they are not the
same. When the frequencies are the same, the VCO is
then “locked” on frequency.
The fV input is produced by dividing the VCO
frequency using the prescaler and N counter in U403.
The prescaler divides by 64 or 65. The divide number
of the prescaler is controlled by the N and A counters
in U403. The N and A counters function as follows:
Both the N and A counters begin counting down
from their programmed number. When the A counter
reaches zero, it halts until the N counter reaches zero.
Both counters then reset and the cycle repeats. The A
counter is always programmed with a smaller number
The synthesizer contains the R (reference), N,
and A counters, phase and lock detectors and counter
programming circuitry.

counter is halted, the prescaler divides by 64.
Where,
N = N counter divide number and
A = A counter divide number.
Example: To illustrate the operation of these
counters, assume a transmit frequency of 858.4875
MHz (channel 300). Since the VCO is the channel
frequency for transmit this frequency is used. To
produce this frequency, the N and A counters are
programmed as follows:
N = 1073
NOTE: Section 7.2.5 describes how the N and A
counter numbers can be calculated for other channels.
A=7
5.2.6 BUFFER AMPLIFIER (Q403/Q404)
To determine the overall divide number of the
prescaler and N counter, the number of VCO output
pulses required to produce one N counter output pulse
can be counted. In this example, the prescaler divides
by 65 for 65 x 7 or 455 input pulses. It then divides by
64 for 64 x (1073 - 7) or 68,224 input pulses. The
overall divide number K is therefore (68,224 + 455) or
68,679. The VCO frequency of 858.4875 MHz
divided by 68,679 equals 12.5 kHz which is the fR
input to the phase detector. The overall divide number
K can also be determined by the following formula:
TCXO and Synthesizer U403. A cascode amplifier is
used because it provides high gain, high reverse isolation and consumes only a small amount of power. The
input signal to this amplifier is coupled from TCXO
Y401, pin 5 by C420. C420 also provides DC
blocking. Bias for the amplifier is provided by R430,
R431, R432, R433 and R428. L402 is an RF choke.
RF bypass is provided by C416, C418 and C419. The
output of Q403/Q404 is coupled to U403, pin 20 by

RF choke to the supply line. Q412 is matched to Q413
by C449, C451 and two sections of microstrip.
VCO and Synthesizer U403. A cascode amplifier is
used because it provides high gain, high isolation and
consumes only a small amount of power. The input
signal to this amplifier is coupled from VCO A007,
pin 6 by C433. C433 also provides DC blocking. Bias
for the amplifier is provided by R450, R451, R453,
R454 and R455. L403 is an RF choke. RF bypass is
provided by C430, C431 and C479. The output of
Q406/Q407 is coupled to U403, pin 11 by a non-polarized capacitor formed by C429/C499.
RF amplifier/buffer Q413 is similar in design to
Q412. The collector voltage of Q413 is switched by
Q405. When the Logic Push-To-Talk (LPTT) on J401,
pin 11 is low Q405 turns on and conducts the 15V
supply to the collector of Q405 and to Q413. The
output of Q413 is matched to 50 ohms by two sections
of microstrip and C465 provides DC blocking. A 3 dB
attenuator follows amplifier Q413. The RF output of
the Exciter is on coaxial connector J402 to the Power
Amplifier.
5.2.8 LOCK DETECT
5.3 75W POWER AMPLIFIER
When the synthesizer is locked on frequency, the
Lock Detect output on U403, pin 2 is a high voltage
with narrow negative-going pulses. When the synthesizer is unlocked, the negative-going pulses are much
wider, the width may vary at a rate determined by the
frequency difference of fV/fR.
5.3.1 AMPLIFIER/PREDRIVER
RF input to the PA from the Exciter is through a
coaxial cable and connector to WO511. C501 couples
the RF to 50 ohm microstrip that connects the input to
U501. U501 is a 6W amplifier/pre-driver operating in
the 851-869 MHz range.
The locked or unlocked condition of the synthesizer is filtered by R440/C423 and applied to J401, pin
16, then sent to the RF Interface on J102, pin 16 for
detection.
Power control is connected to WO505 from the
RF Interface board (RFIB). RF is filtered from the
control voltage line by various capacitors and inductors to U501, pin 2. This control voltage regulates the
RF output of the amplifier on U501, pin 4 to approximately 5W.
VCO and exciter RF stages. A cascode amplifier is
used because it provides high gain, high isolation and
consumes only a small amount of power. The input
signal to this amplifier is tapped from VCO A007, pin
4 by C441. C441 also provides DC blocking. Bias for
the amplifier is provided by R464, R465, R466, R467
and R468. L406 is an RF choke and R483 lowers the
Q of the coil. RF bypass is provided by C434, C442,
C445, C443, C444 and C480. The output of Q410/
Q411 is matched to the Exciter RF stages by C446,
R450 and two sections of microstrip.
5.3.2 DRIVER
The output of U501 passes through several
sections of 50 ohm microstrip and matching capacitors
to the emitter of Q501. Driver Q501 is a common base
amplifier with a normal output of approximately 22W.
Supply voltage is RF bypassed by various capacitors
and microstrip. C519, C520, C521 and microstrip
match the output of the driver to 50 ohms at J501.

5.3.5 THERMAL SENSOR
70.7-ohm Wilkinson splitter and then to the emitter of
each common-base amplifier. The 60W outputs on the
collectors of the amplifiers are combined using a
Wilkinson combiner. Q502 has a half-wave transmission line on the input and Q503 has a half-wave on the
output. These T-lines are used to drive the 60W amplifiers out of phase. The output of the combiner is fed
from WO513 directly to the forward/reverse power
detect board.
Thermal protection is provided by temperature
sensor U503. The operating range of the sensor is
from –30° C to 100° C (–22° F to 212° F). CR505 is
used to reference U503 above ground to allow the
sensor to read below 0° C. Amplifier U502A sends the
output of U503 through WO509 to the RF Interface
Board. The RF Interface Board reduces the power
amplifier to half power (via the MPC) if the temperature reading is too high and turns the fan on and off
(not via the MPC). The fan is turned on at approximately 50°C and off again at 42°C.
The Wilkinson splitter and combiner provide the
capability to split the drive input and combine the
final outputs while maintaining isolation between the
two final amplifiers. The combiner consists of two
quarter-wave transmission lines and a balancing
resistor. During normal operation, a signal of relatively equal phase and amplitude is present on both
ends of the balancing resistor. Therefore, no current
flows and no power is dissipated in the balance
resistor. If one final failed, the other final of a pair
would continue to function.
5.3.6 FORWARD/REVERSE POWER DETECT,
CIRCULATOR, LOW-PASS FILTER
The power amplifier output is directly coupled to
the forward/reverse power detect board via a jumper.
The output then enters the circulator and exits to the
low-pass filter board and the antenna jack for a
minimum power output of 75W at the default setting.
If an antenna is not connected, the circulator connects
the output power to R685.
5.3.4 POWER DETECTORS
Electromagnetic coupling is used to sample the
output of each final amplifier. The RF is then fed to a
rectifier to create a voltage indicative of the power
output. The outputs of U504A and U502B are monitored by the repeater software through the RF Interface Board. If a final amplifier fails, the software will
reduce the output power to prevent overdriving the
remaining final amplifier.
Forward and reverse power are electromagnetically coupled from the input and reflected ports of the
circulator. R663/R680 calibrate the forward and
reverse sense levels. The sensed levels are coupled to
the RF Interface Board and software.

CIRCUIT DESCRIPTION
5.4 175W POWER AMPLIFIER
The Wilkinson combiners provide the capability
to split the drive input and combine the final outputs
while maintaining isolation between the final amplifiers. Each combiner consists of two quarter-wave
transmission lines and a balancing resistor. During
normal operation, a signal of relatively equal phase
and amplitude is present on both ends of the balancing
resistor. Therefore, no current flows and no power is
dissipated in the resistor. If one final failed, the other
final of a pair would continue to function.
5.4.1 GAIN BLOCK
RF input to the PA from the Exciter is through a
coaxial cable and connector to WO509. RF is directly
coupled to 50-ohm microstrip that matches the input
to U501. U501 is a 20W amplifier/pre-driver operating in the 851-869 MHz range.
Power control is connected to WO505 from the
RF Interface board (RFIB). RF is filtered from the
control voltage line by various capacitors and inductors to U501, pin 2. This control voltage regulates the
RF output of the amplifier on U501, pin 5 to approximately 12W (see Figure 5-6).
5.4.4 POWER DETECTORS
Electromagnetic coupling is used to detect the
output of each final amplifier. The detected RF is then
fed to a rectifier to create a voltage output indication
of the power output. The outputs are monitored by the
RF Interface Board and the station software. If any of
the finals fails, the software will reduce the output
power to prevent overdriving the remaining final
amplifier.

The output of U501 passes through several
sections of 50 ohm microstrip and matching capacitors
to the emitter of Q502. Driver Q502 is a common base
amplifier with an output of approximately 60W.
Supply voltage is RF bypassed by various capacitors
and microstrip. C551 and C568 match the output of
the driver to the input impedance of the splitter to the
final amplifiers.
5.4.5 THERMAL SENSOR
Thermal protection is provided by temperature
sensor U503. The operating range of the sensor is
from 0 to 100° C (32° F to 212° F). Amplifier U502A
sends the output of U503 to WO519 and to the RF
Interface Board. The RF Interface Board reduces the
power amplifier to half power (via the MPC) if the
temperature reading is too high and turns the fan on
and off (not via the MPC). The fan is turned on at
approximately 50°C and off again at 42°C.
5.4.3 FINAL AMPLIFIERS
The output of the driver is DC blocked through
C552 and is connected to the first 70.7 ohm splitter
with a 50 ohm microstrip. One output of the first
splitter is sent directly to another 70.7 ohm splitter to
feed Q703/Q704. The second output of the first
splitter is connected to the splitter driving Q701/ Q702
through a half-wave 50 ohm microstrip. The 60W
output of Q701/Q702 is combined through a 70.7 ohm
quarter-wave Wilkinson combiner and fed through a
50 ohm microstrip to the final 50 ohm combiner.
5.4.6 FORWARD/REVERSE POWER DETECT,
CIRCULATOR, LOW-PASS FILTER
The power amplifier output is directly coupled to
the forward/reverse power detect board via a jumper.
The output then enters the circulator and exits to the
low-pass filter board and the antenna jack for a power
output of 175W (±7W). If an antenna is not
connected, the circulator connects the output power to
R685.
Outputs from amplifiers Q703/Q704 are fed to
the final combiner through 50 ohm microstrip that is a
half-wavelength longer than the other side. The 25
ohm output impedance of the final combiner is transformed to 50 ohms through a quarter-wave, 35.35 ohm
microstrip. The output of the quarter-wave transformer is fed directly into the forward power detector
via W510.
Forward and reverse power is electromagnetically coupled to the detectors on the input and
reflected ports of the circulator. R663 and R680 calibrate the forward and reverse sense levels. The sensed
levels are coupled to the RF Interface Board and software.

CIRCUIT DESCRIPTION
5.6 800W POWER SUPPLY
C110/C111. The resistor network connected to CR104
charges up C106/C107 to +18V off the line. This
provides the bias voltage required to start the
controller IC U102. Once the IC turns on, current is
being switched on L107. A small tap winding on L107
provides sustaining current to the U102. When AC is
first connected, it could take several seconds for C106/
C107 to charge to +14V before the unit starts.
WARNING
This power supply has voltage potentials greater than
400V which can cause serious injury or death.
Dangerous voltages may even be present several
minutes after power is removed until they bleed down
to safe levels. Therefore, because of this and the
complexity of the switch-mode power supply, it is
strongly recommended that it be returned to the
EFJohnson Company for repair (see Section 1.7).
U102 samples the input voltage through R105/
R106/R107, the input current through T103/T104/
CR146/CR108/R113/R114, and the output voltage
through the divider at R127. U102 modulates the duty
cycle to MOSFET Q101 such that the input current is
shaped like, and in phase with, the input voltage.
5.6.1 FILTER BOARD
AC power is brought into the power supply
through the IEC AC connector on the front panel of
the power supply. This connector is attached to EMI
Filter Assembly, Part No. 023-2000-820. The filter
contains common mode and differential mode filtering
so that the supply complies with FCC Class-A
regulations.
The controller has two feedback loops: a voltage
loop to keep the 400V constant and a current loop to
keep input current correct. Compensation for the
current error amp is C120/R141/C121 on U102, pin 1.
Compensation for the voltage error amp is provided by
C127/C142/C126 on U102, pin 16. U102, pin 4 and
associated circuitry automatically adjust the Power
Factor Correction (PFC) for input voltage (100-240V
AC), line frequency (50-60 Hz), and load on the power
factor.
In addition to the filter components (C1, C2, L1,
C3, C4, L2, C5), R1 is used to discharge the filter
capacitors when AC is removed. Metal-oxide varistors (RV001/RV002) are placed across the line on the
input and output of the EMI filter that clamp transients
on the AC line to prevent damage to the power supply.
The AC power is fused with F001 after the connector
and before the filter. Replace this fuse with a 15A
250V (314015) fuse.
WARNING
The output voltage of the power factor section is 400V
DC. This voltage is bled off slowly. After turning
power off, it can take more than 5 minutes to
discharge.
At the output of the filter board is a bridge rectifier. The rectifier is heat sunk to the filter bracket
through a Grafoil thermal interface pad. Filtered AC
power is connected to the main board via wires W001
and W003. Filter and rectified current is brought to the
main board via wires W004 and W005. The safety
ground is connected from the filter board to a stud in
the chassis through W002.
5.6.3 MAIN PULSE WIDTH MODULATOR
The +26.5V output is created from a two-transistor forward converter (Q116/Q118). It uses the
400V output of the power factor correction on C110/
C111 for an input voltage. The same controller IC
(U102) drives the +26.5V stage. This stage runs at
exactly twice the power factor correction frequency
and uses trailing edge modulation. The pulse width
modulator uses the PFC supplied current for modulation scheme that reduces ripple current in C110/C111.
5.6.2 POWER FACTOR CORRECTION
The power factor switching frequency is set at
87.5 kHz, ±5 kHz. The average current mode boost
converter is comprised of L107, Q101, CR145, C110,
and C111. Half of U102 is used for power factor
correction. RT101/RT102 are negative temperature
coefficient thermistors that limit the in-rush current to
The output of the IC, U102, pin 11 is fed to a
level shifting gate drive network comprised of C139,
C140, T106, C136, C197, C137, and C228. Each

CIRCUIT DESCRIPTION
CIRCUIT DESCRIPTION
R176, and CR122, along with U104B, create a very
narrow pulse on U104B, pin 6. Q110, Q111 and Q112
level shift and buffer this pulse. When the narrow
pulse is presented to the timing capacitor of the +15V
and +5V converters, the cycle terminates and a new
one starts. This forces the +15V and +5V converters to
run at the same frequency, and is slightly delayed from
the +26.5V converter.
converter has a gate protection zener diode CR117,
CR120, respectively. In addition, each power
MOSFET has a gate turnoff network.
In operation, power MOSFETs Q116, Q118 are
on for approximately one-third of the period providing
current to the primary side of T107. During that time
CR121 is forward conducting and charging L101.
When the MOSFETs are switched off, the magnetizing current of T107 continues to flow through
CR118, CR119. These diodes place 400V across the
transformer in opposite polarity that resets the transformer core. During the off period, CR128 is free
wheeling and L101 is discharging. Transformer T107
provides the isolation between the low voltage and
high voltage sections.
5.6.5 FAN AND THERMAL SHUTDOWN
The voltage supply to the thermal measurement
circuit is generated from transformer T101 and the
associated bridge rectifier consisting of CR101,
CR102, CR110, CR111, and bulk storage capacitor
C101. This voltage is approximately +9V when the
AC voltage is at 120V AC.
The +26.5V pulse width modulator is peak
current mode controlled. This type of converter
requires current and voltage sense. T105, CR112,
R125, R146 and C125 provide the current sense
circuit. The voltage sense circuit is U109 and the associated circuitry on the isolated side of the supply.
NOTE: This DC voltage is dependent on the input AC
voltage.
U106 provides a very accurate +5V supply that is
required for proper operation of the temperature sense
circuit. A precision temperature sensor (U101) is
mounted to the +26.5V rectifier heat sink. The output
of this sensor is 10 mV/°C with a ±1% accuracy. This
voltage is amplified by U110A, with precision resistors R183/R184 setting the gain.
An opto-isolator is used to cross the boundary
from high to low voltage sections. In the event of an
over-voltage condition (>+32V), U115 and associated
components turn the power supply off. This shutdown
mechanism latches the power supply Off. The enable
line must be turned Off for 10 seconds for the power
supply to reset. T106 has a tap to provide current to
the optional battery back-up board (Part No.
023-2000-830). The +26.5V is available at the high
current output connector to the power supply and it
also powers the +15V, +5V and -5V converters
through F102.
The output of gain stage U110A is fed to the
computer interface via WO116 so that power supply
temperature can be monitored with the repeater
programming setup. The output of U110A, pin 3 is
also connected to the thermal shutdown circuit
U110C, R135, R136, R137, R138, and R139. If the
heat sink temperature reaches 92°C (198°F), the
output of U110C, pin 8 goes high and saturates Q103.
When Q103 is turned on, U107 is turned off and the
power supply turns off. The remote voltage is always
present so that when the heat sink temperature drops
to 80°C (176°F), the power supply restarts. The high
temperature condition would only exist if the fan was
blocked or faulty.
5.6.4 SYNCHRONIZING CIRCUITS
The +15V and +5V sections run at the same
frequency as the +26.5V pulse width modulator. In
order for a beat note not to be produced, a sync circuit
is used. If two converters are not synchronized, the
difference frequency may show up at an undesired
location in the repeater.
The output of U110A, pin 1 also connects to the
fan controller. U110D with the associated resistors
provides a means to turn the fan on/off. Transistors
Q120/Q121 provide current gain and a voltage level
shift to run the fan. The fan turns on when the heat
sink reaches approximately 45°C (113°F) and turns
Divider R151/R152 samples the output of the
main pulse width modulator. When Q116 and Q118
turn on, the output on U104A, pin 3 goes high. C138,

off again when the temperature reaches 35°C (95°C).
It is normal for the fan to intermittently turn on and
off.
Sync pulse is added into the low side of C176 via
C172 and R225. The free running frequency of the
15V converter (approximately 145 kHz) is set about
10% lower than the 26.5V converter. This longer duty
cycle allows the sync circuit to synchronize the
converter.
5.6.6 +15V CONVERTER
The input voltage to this “Buck” DC/DC
converter is the main +26.5V output fused through
F102. The bias voltage for the controller IC U112, pin
15 is provided by a +15V regulator U111. The basic
buck converter consists of MOSFET Q125, Schottky
diode CR126 and storage inductor L102. C165, C166,
C167, L103, C169, and C170 filter the output voltage
and attenuate the ripple at the switching frequency
(160 kHz). The capacitors are an integral part of the
feedback loop. The duty cycle is approximately 60%.
Over voltage is sensed using U116 as a reference
and amplifier, CR129, acts as a crowbar on the output.
Once the crowbar is turned on, opto-isolator U119 is
activated to shut down the power supply. The enable
line must be toggled or AC voltage removed for 10
seconds to reset the power supply.
The +15V buck converter is peak current mode
controlled. T108 samples the inductor current while
MOSFET Q125 is on. The sampled current is translated to a voltage via CR127, R209 and R210.
5.6.7 +5V CONVERTER
Operation of the +5V “Buck” DC/DC converter
is the same as the +15V, except slop compensation is
not required. Some values are different to get the 5.2V
DC and current limit to 6A. The duty cycle is approximately 20%.
Because the MOSFET is a high-side switch, a
charge pump is required to get the gate voltage above
the input voltage. The charge pump operates as
follows: When the output from IC U112, pin 14 is low,
capacitor C162 is charged through CR124, R198,
R199, R200 so that Q122/Q123 are off. When U112,
pin 14 goes high, the capacitor stays charged and
CR124 is reverse biased. Q122/Q123 are turned on
which forward biases CR125 and applies a gate-tosource voltage of approximately +12V. During this
time Q124 is off. When U112, pin 14 goes low, Q124
turns on and rapidly discharges the gate capacitance.
Resistors R231/R208, coupled with C164, provide
snubbing for Schottky diode CR126.
5.6.8 -5V CONVERTER
The –5V “Buck-Boost” converter scales and
inverts the voltage. This converter is free running at
approximately 75 kHz. The output switch and
controller are built into the 5-leg TO-220 IC U114.
L105 is the storage inductor. C204, R270 and R271
close the voltage feedback loop and are set for
optimum stable transient response. C208/C209 reduce
output ripple. Under-voltage protection is required on
this stage and works the same as the over-voltage
protection of the +15V and +5V buck converters, but
has opposite polarity.
Because the +15V converter operates at greater
than 50% duty cycle, slope compensation is required.
Capacitor C176 is the time capacitor for this converter
and R223 is the resistor that sets the charge current. A
sawtooth wave is present on the high side of C176 that
is buffered by Q127/Q128. The resistor divider
network of R315, R227, R229 and R232 provide the
correct amount of compensation for stable operation
and current limiting.
5.6.9 POWER SUPPLY REPAIR AND
ALIGNMENT
If a power supply fails, it is typically a power
MOSFET or power diode that fails. In some cases the
MOSFET gate may short and cause some of the driver
circuits to be damaged. When replacing heat sunk
components, it is advisable to replace the sil-pad
thermal interface material at the same time. The
mounting hardware must be replaced exactly as built
The output voltage is sampled by R215, R216,
and R217 and sent to the inverting side of the error
amplifier internal to the controller IC on U112, pin 1.

load status.
in the factory. The mounting screws for the power
semiconductors MUST BE torqued to 4-5 in/lbs.
Under or over torque can shorten the life of the semiconductor.
NOTE: If using a generator, the DC voltage must be
between 23-28.5V (26.5V DC is recommended), and
ripple voltage must be less than 1% or approximately
0.25V P-P.
The majority of the voltage and current limits are
set with fixed value components in the power supply.
However, the +26.5V, +15V and +5.2V supplies are
adjustable. When certain components are replaced, the
voltages must be adjusted. The voltages should be set
at light load (i.e. repeater in the receive mode).
5.7.2 CHARGER
The charger charges the batteries when the
repeater is on and switch S101 is “On”. A tap off of
the main transformer of the power supply through
wire W104 and a +26.5V line via wire W102 are what
supply the charger with the necessary voltage to
charge the batteries. The tap off of the transformer is
biased by the +26.5V and then filtered through L101,
C105 and C119. Since the tap from the power supply
is not a regulated voltage, bleeder resistors R136/
R137 dissipate some power when the batteries are
fully charged. In a no load situation, the peak voltage
of the tap is approximately 63V and it is not impressed
across the 50V capacitors C105/C119. During a
battery charging condition, the line voltage to the
charger on U107, pin 2 should be about 35V.
1. The +26.5V supply can be adjusted with R174 when
any of the following components are replaced:
R173, R174, R175, U109, U108, U102, R143,
R170 or R171.
2. The +15V supply can be adjusted with R216 when
R215, R216, R217 or U112.
3. The +5.2V supply can be adjusted with R254 when
R253, R254, R255 or U113.
5.7 BATTERY BACK-UP MODULE
While charging batteries, if the charge voltage is
varied with respect to the temperature of the batteries,
the life of the batteries is increased dramatically.
Figure 5-9 shows the algorithm used in float charge
applications for two 12V lead-acid batteries in series.
It shows that the charge voltage should be 27.3V DC
±0.15V at 25°C (77°F) with –55 mV/°C temperature
compensation.
5.7.1 OPERATION
When an optional battery back-up module is
installed in a power supply, it performs the function of
powering the repeater in the absence of AC voltage.
When AC is present, it can be used to charge a pair of
lead-acid batteries in series. The charger is a temperature compensated constant voltage charger. The
maximum output current from the charger is 2.2A.
The charger works when AC is present and the
repeater is enabled. The charger switch on the battery
back-up module must be “On”. The temperature
compensation thermal sensor is part of Part No. 0232000-223 battery back-up module cable assembly.
An LM317M linear voltage regulator (U107) is
used to create the temperature compensated charge
voltage. This device is capable of delivering 2.2A of
continuous current to the batteries.
To create a temperature compensated voltage, an
op amp (U104) is used as a voltage gain device from a
temperature probe attached to the batteries (part of
cable Part No. 023-2000-223). This op amp with
R148/R149 defines the slope for the algorithm in
Figure 5-9. The output of the temperature compensation network is attached to the adjust pin of U107.
R138-R140 allow the output voltage to be set properly
at a given ambient temperature. F101 is a 4A resettable fuse used to prevent thermal run away in the
When AC is low or not applied to the power
supply, the battery input takes over if the voltage is
within range. The input voltage to the battery back-up
module acts as the 26.5V supply and the other voltages in the power supply also are present (+15, +5.2
and –5V). When AC is restored, the battery back-up
module disengages automatically. The change over
from battery to AC or AC to battery may cause the

event of U107 failure. If the output current to the
batteries exceeds 4A, this fuse opens. Once the current
drops below 100 mA, the fuse closes automatically.
CAUTION: Exceeding –30V across the battery backup terminals with the power supply on will destroy
Q105.
NOTE: If any of the charging components are replaced,
R140 needs to be adjusted to set the output (battery
back-up battery terminals) voltage to 27.3V ±0.15V
when temperature sensor is at 22°C (71.6°F)
.
Charger Voltage
5.7.4 ENGAGING THE RELAY
The main purpose of the Battery Back-Up
Module (BBM) is that when the power supply loses
AC line voltage, a pair of series connected 12V lead
acid batteries (approximately 26.4V) or other 2328.5V DC source will engage to the supply allowing
the repeater to operate. To perform this function a
voltage comparator (U101) is used to monitor the
charge tap coming from the power supply.
30V
-55mV/°C
27.3V
A 2.5V reference voltage is supplied to the
comparator from U102. The transformer tap voltage is
smoothed and divided by CR114, C118, R116, R121
and R122. The values for these components were
calculated so that when the AC line voltage is dropped
to 70V AC, the output of the comparator turns Q103/
Q102 on which in turn engages the relay K101. The
relay is capable of 30A which delivers the battery
energy to the power supply via W102 with the return
line being W103.

5.7.3 REVERSE BATTERY PROTECTION
NOTE: When AC is restored, the relay disengages and
the charger automatically begins to charge the
batteries.
To obtain reverse battery protection, a number of
techniques are implemented. Q108/Q110 are arranged
in a Darlington configuration to isolate the output
capacitors C109-C111 from conducting in the event
the batteries are connected backwards. This circuit
also provides a means to turn the battery charger off in
case the user wants to run the repeater off another DC
source. S101 opens the base of Q105 which turns off
Q104. CR111 is a green LED located on the right side
of the battery back-up module when looking at the
front of the power supply. It tells the user the charger
is in charge mode and is marked “On”.
5.7.5 OVER/UNDERVOLTAGE SHUTDOWN
U101 is a quad comparator IC used to create the
over voltage and under voltage shutdown circuitry. If
the batteries are drained sufficiently enough such that
the voltage of the batteries drops below 20.3V DC, the
output of the comparator goes low and turns Q102 off.
By turning Q102 off, the batteries are switched out of
the circuit. The batteries cannot be switched back into
the repeater until the voltage rises to 22.6 VDC. This
operation is in place to protect the repeater and the
batteries. In the event the batteries are over charged, or
the repeater is driven by the generator that has the
voltage set too high, the relay will disengage above
30.5V DC. In order to switch the batteries back to the
repeater, the voltage must drop below 29V DC.
To notify the user that the batteries are connected
improperly, R101/CR101 are connected in series
across the batteries. CR101 is a red LED that lights
when the batteries are connected backwards and is
located on the left hand side of the battery back-up
module when looking at the front of the power supply.
This LED is marked “Reverse Bat.”. CR113 eliminates a path for the reverse battery current through the
relay and over/under voltage protection circuitry.

5.8 CARD RACK
5.7.6 BBM FAN CONTROL
The card rack provides slots for up to eight logic
cards; including Main Processor Card (MPC), Main
Audio Card (MAC) and the Interface Alarm Card
(IAC). The IAC has a notch in the card to accommodate a pin in Slot-8 so that no other card can be
plugged into this slot.
The voltage supply to the thermal measurement
circuit is taken from the 26.5V DC line into the BBM.
A precision temperature sensor (U106) is mounted on
the PC board near a screw into the BBM bracket
which transfers heat to the sensor. The output of this
sensor is 10 mV/°C with a ±1% accuracy. This voltage
is amplified by U105 with resistors R153/R154 setting
the gain.
On the back of the card rack is the Backplane
with plug-in connectors to the cards and cables to the
RF modules, Power Supply and External Connector
Board.
The output of this gain stage (pin 1) is fed to
another gain stage that performs as a comparator. The
output (pin 7) will go high when the heat sink temperature reaches 45°C and will go low when the tempera-

5.10 MAIN PROCESSOR CARD
5.10.1 INTRODUCTION
The Main Processor Card (MPC) connects to the
computer with repeater software to program the
repeater parameters, sets and reads the alarms, handles
communication between repeaters, maintains the
audio gating for the MAC, handles initialization
requests from cards and contains the repeater RF data
for the Receiver, Exciter and CWID.
5.10.2 MAIN CONTROLLER MICROPROCESSOR (U27)
This contains the main software and control over
the repeater (see Figure 5-12).
Control functions for each repeater are performed
by the Main Processor in the MPC installed in each
repeater. The MPC contains the main software and
control over the repeater via microprocessor U27 (see
Figure 5-17).
The main controller (U27) is a VLSI (Very Large
Scale Integration) CMOS 16-bit single chip computer
with an 8-bit external data bus. This processor has
software compatibility with the V20 (8086/8088),
faster memory access, superior interrupt processing
ability, and enhanced control of internal peripherals.
This ROMless processor has a variety of on-chip
components including 256 bytes of RAM, serial and
parallel inputs/outputs, comparator port lines and
timers.
Information is exchanged between repeaters via a
High-Speed Data Bus (HSDB) that interconnects all
the MPCs. This control technique is called distributive
processing and it eliminates the need for a separate
system controller at each site. The HSDB processor
(U13) on the MPC provides these control functions.
The MPC also contains:
•
Flash Memory, RAM, non-volatile EEPROM.
•
I/O chip select to allow the addressing of data
latches for Input/Output.
•
Read/Write selection to be sent and received on the
Controller Backplane.
•
Clock line, data line and chip select line from the
IAC to load the Receiver and Exciter synthesizers.
•
Serial communication circuitry and processes for
the High Speed Data Bus (HSDB).
•
Asynchronous parallel communication to the other
cards, i.e. alarm input and output circuitry.
•
AC Power Failure indication from the IAC.
•
Provides an output from the IAC to the power
amplifier to control the output power.
•
Exciter Logic Push-To-Talk (PTT).
Receiver synthesizer lock, Exciter synthesizer lock,
thermal level from the power amplifier, VSWR
level from the PA, forward power level, RSSI signal
level, audio levels from the MAC, Receiver and
Exciter from the IAC.
Eight banks of registers are mapped into internal
RAM below an additional 256-byte special function
register (SFR) area that is used to control on-chip
peripherals. Internal RAM and the SFR area are
together and can be relocated anywhere in the 1Mbyte address space. This maintains compatibility with
existing system memory maps.
The two microprocessors and USART (U22) are
reset by integrated circuit U17. Reset occurs when
power is turned on, when the 5V supply drops below a
threshold level or the reset switch (S1) is active.
When a microprocessor is reset, several internal
registers are cleared and the program is started over
from the beginning. Low-voltage reset prevents
improper operation resulting from low-voltage conditions.
When power is turned on, the RESET output U17, pin
6 is initially high and the inverted RESET output U17,
pin 5 is initially low. Once the 5V supply stabilizes,
these outputs remain in these states for approximately
100 ms to ensure that reset occurs. This time delay is
set by capacitor C14 connected to U17, pin 3. If the 5V
supply drops below a nominal level, the RESET
outputs change states and microprocessor operation is
interrupted until the 5V supply returns to normal. C3

ports are designated P0, P1, P2, P3. P0 is used as a
data bus. Ports P1 and P2 are always used as general
purpose inputs/outputs. P3 is used for specialized
functions, i.e. a serial port (RxD/TxD) and interrupt
(INT).
Provides a means of transferring data to and from
the CPU on the MPC, memory storage on each card
and peripheral devices in and out of the MAC and
IAC.
The operating speed of the microprocessor is set
by an 12 MHz clock generated by Y2. This clock
frequency is divided down by an internal divider to
provide a machine cycle time of 2.5 µs. Most program
instructions are executed in one machine cycle and
none require more than four machine cycles.
Pin 15
MREQ
A memory request line operates in conjunction
with the Read/Write lines. These provide the ability to
read from or write to the main processor memory on
the MPC.
The microprocessor U13 communicates with the
main processor (U27) through U9 and U10. U9 is a
Transmit FIFO (First In First Out) and U10 is a
Receive FIFO. This combination makes up an asynchronous parallel-to-parallel interface to the Main
Processor.

Microprocessor U13 also calculates the current
system priority for the channel. This priority is from
the programming software responses and the current
priority is sent to the main processor. U13 also reads
repeater number and channel number information in
memory. U13 also determines the current free repeater
and includes that information in the data sent to the

This interconnects all repeaters to provide an
exchange of information. This control technique is
called distributive processing and eliminates a separate system controller at each site. Information on this
bus indicates which repeaters are in use and also
which mobiles are using the system. This

CIRCUIT DESCRIPTION
When it is time to transmit the CW Identification,
the main processor on the MPC sends the identification to U111 via the data bus and U160 (Rx FIFO).
The CWID is sent to the Tx Data Amplifier and Filter.
The output of the filter is summed with the transmit
audio and sent to the Exciter.
latches open and close gates to route a path for the
audio or data.
Audio control functions for each repeater are
performed by the Main Processor in the MPC. The
MPC contains the software and maintains control over
the repeater via microprocessor U27. The audio/data
microprocessor passes received data to the main
processor, and it is given the programmable parameters for the gates.
U111 also uses six octal latches to provide additional input and output lines. Latch U107/U108
provide outputs which allow U111 to control various
audio gates. These gates control the CWID, FSK data,
and receive/transmit audio signals.
Information is exchanged between the cards in
the Controller Backplane via a data bus and an address
bus. The address bus provides the link between the
main processor and the chip and the address latches on
the MAC. These latches control the octal latches that
select the audio and data gates. The data bus is the link
between the Main Processor and the Audio/Data
Processor on the MAC. The Main Processor controls
the data to the octal latches and opens and closes the
gates required to route audio/data in and out of the
repeater. The MAC also contains:
•
The audio interface between the receiver and exciter
and to the external connections.
•
The receive audio filtering with de-emphasis.
•
The squelch filter and detector.
•
Slow decay timing circuit that controls a mute gate
on the main receive audio.
•
A filter, DC restoration and slicer circuitry for
detecting the subaudible data.
•
The fast squelch and data fed to the microprocessor
that decodes the data and uses the squelch line as a
data qualification signal.
•
Latch U106 provides outputs which allow U111
to route signals to the Audio/Data Test Point by
switching gates on and off. U106 also provides adjustment of the selected EEPOTs.
U155-U156 allow U111 to select the EEPOT to
adjust with chip select lines. These latches also
provide routing of some audio/data signals through
gates.
In addition, U111 controls the receive and
transmit audio gates, receiver squelch, several frontpanel indicators, and other functions. U111 encodes
the data messages transmitted to mobiles monitoring
that channel, and controls transmitter keying.
5.11.3 RECEIVE AUDIO
The Receive Wide Band Audio (RX WBAND)
signal from the Receiver is fed into the MAC on P100,
pin 27. This audio signal includes; audio, LTR data,
and noise. The audio processing circuit provides
filtering and amplification of the audio signal before it
is routed to the outputs on the MAC card.
A low-pass filter consisting of U121A/B attenuates frequencies above 3 kHz. This removes highfrequency noise from the audio signal. From the filter
the signal is fed to amplifier U122A to increase the
level before the high-pass filter to preserve adequate
hum and noise ratio.
Transmit audio filter and limiter with pre-emphasis.
5.11.2 AUDIO/DATA MICROPROCESSOR
(U111)
This Audio/Data microprocessor is on the MAC
card and is used to decode LTR data received from the
mobiles. The LTR data is applied to U111, pin 8 (P1.7
input). When a word is successfully decoded the data
is then sent to U161 (Tx FIFO) and transmitted on the
data bus in parallel to the main processor on the MPC.
From the audio amplifier the signal is fed to a
high-pass filter consisting of U122B/C/D. This filter
attenuates frequencies below 300 Hz which removes
data present in the wide band audio signal. These
filters are configured to act like large inductors. The
5-31

Part No. 001-2008-203
CIRCUIT DESCRIPTION
5.11.5 RECEIVE DATA CIRCUITRY
signal is then fed to U163A which provides 6 dB per
octave de-emphasis.
The receive wide band audio signal is the unfiltered output of discriminator U202 in the Receiver.
Therefore, this signal contains audio, LTR data, and
noise. A low-pass filter formed by U124A/B attenuates frequencies above 150 Hz by 24 dB per octave so
that only the data frequencies are passed. From the
filter the signal is fed to amplifier U125A. The gain of
U125A is adjusted by a level control. The output of
U125A can be routed through Data To Audio/Date
Gate U159C and the Audio/Data Test Point J100.
Audio gates U113B/C/D permit noise squelch
circuit, control logic, and audio switch to control
gating of the audio signal. The control signal from the
noise squelch circuit is applied to U113B through
U113D. When a carrier is detected, this input is high
and U113B passes the signal. Programming determines the gating of audio. When audio is passed by
U113B/C and U114A, the audio can be routed through
other gates to various outputs (see Section 5.11.6).
5.11.4 RECEIVE SQUELCH CIRCUITRY
DC restoration circuit converts the data signal
from AC floating near ground to a digital signal at
levels of 0 and 4.5V. U125B/C provide the reference
voltage on the inverting input of comparator U125D.
Positive peak detector U125B handles the positivegoing peaks of the data signal. Negative peak detector
U125C handles the negative-going peaks of the data
signal.
The receive wide band audio includes audio, data
and noise. The squelch circuit detects this noise to
determine receive signal strength. When no carrier or a
weak carrier is received, there is a large amount of
noise present. Conversely, when a strong carrier is
present, there is very little noise present.
The voltage on non-inverting input to U125D is
midway between the positive- and negative-going
peaks. The data input is on the non-inverting input of
U125D. When the data signal rises above the reference
voltage, the output goes high. Conversely, when the
input voltage drops below the reference voltage, the
output goes low. The receive data is then passed to
audio/data processor U111.
U135A is a high-pass filter which attenuates
frequencies below approximately 30 kHz so that only
high-frequency noise is passed. This noise is amplified
by U135B and U123A. A level control adjusts the gain
of amplifier U135B. The gain of U123A is partially set
by a thermistor to compensate for circuit gain and
noise level changes caused by temperature variations.
The amplified noise is then applied to a bridge
rectifier. The difference between bridge rectifier
outputs is applied to the inputs of U123B. The output
of U123B is positive-going pulses. These pulses are
applied to U123C which is a Schmitt trigger. When the
input signal rises above the reference the output goes
low and causes the reference voltage to decrease
slightly adding hysteresis to the triggering level. This
hysteresis prevents intermittent squelching when the
receive signal strength is near the threshold level.
5.11.6 RECEIVE AUDIO PROCESSING
The receive audio signal is fed into the MAC on
P100, pin 27. When a mobile-to-mobile call is
received, Repeat Gate U153C is enabled and the
receive audio signal is routed through Transmit Option
Gate U158C to the input of the transmit audio buffer
U164B to be retransmitted. Repeat Gate U153C is
controlled by processor U111 through latch U107. A
logic 1 on the control input causes the signal to be
passed.
The output of U123C is applied to U123D and
Logic Squelch to Audio/Data Gate U159B and audio/
data processor U111. Gate U159B routes the squelch
output to the Audio/Data Test Point J100. U123D
functions as a timing buffer. The output of U123D is
applied to Receive Squelch Active Gate U113D. When
this gate is closed, the squelch circuit controls Normal
Receive Gate U113B to block receive audio if no
signal is present.
May 1998
Part No. 001-2008-203
When the received audio must be routed to the
backplane (i.e. for other cards), Receive Voice Gate
U115B is enabled by processor U111/latch U108 and
passes the audio signal to amplifier U120B. Receive
To Backplane (RX TO BP) U115C is enabled and
passes the amplified audio to the backplane.
5-32
CIRCUIT DESCRIPTION
Buffer U164B combines the microphone audio
signal from U164A with the audio signal from the
Repeat Gate U153C.
When the audio received must be routed to the
external speaker or speaker/microphone, Local Audio
Mute Gate U114D is enabled by U111/latch U108.
The audio is passed to local audio output amplifier
U132. The gain of U132 is adjusted by the local audio
volume control and on/off switch.
5.11.7 VOTER AUDIO
U127B/C form a high-pass filter that attenuates
frequencies below 300 Hz to prevent interference with
the LTR data applied at U129B. Pre-emphasis at 6 dB
per octave is provided by an RC combination before
the signal is fed to the Limiter U127D.
When used, the Receive audio from the voter
receiver comes into the MAC on P100, pin 25. Amplifier U120A sets the gain of the signal and the output is
routed to Voter Audio Mute Gate U115A. The gate is
controlled by A/D processor U111/latch U108. If the
gate is enabled, the audio goes to the Receive Mute
Gate U113C and passes throughout the MAC Card.
Limiter U127D and rectifiers form a precision
limiter which prevents over modulation caused by
high-level input signals. With normal input levels, the
output of a bridge rectifier follows the input of the
bridge. When a high-level signal is applied to the
bridge, the bridge opens and the output of the bridge is
limited to a specific level.
5.11.8 COMPANDOR OPTION
The output of the limiter passes to a composite 6pole splatter filter formed by U127A, U128D and
U128A separated by buffers U128B and U128C.
The compandor option enhances the receive and
transmit audio when used in conjunction with the Telephone Interface Card (TIC) in LTR systems.
The output from U128A is fed to Normal Modulation Mute Gate U118B that is controlled by A/D
processor U111/latch U106. When enabled, the gate
passes transmit audio to EEPOT U149. U149 is an
electronically adjustable potentiometer that adjusts the
gain of transmit audio amplifier U129C. The gain of
U129C can only be adjusted through the software.
Therefore, a computer must be attached to the MAC
card when levels are set.
The filtered Receive Audio passes through the
Receive Mute Gate U113C to the expander input on
A301, pin 1. The expand output of A301, pin 2 is
coupled to the audio outputs by U114C.
The TX-VOICE from P100, pin 32, passes
through TX Voice Gate U158A to the expander input
on A301, pin 5. The compressed output of A301, pin 4
is passed to the TX Audio Buffer.
The output of U129C is fed to summing amplifier
U129B where it is combined with LTR transmit data
and CWID when present. The gain of audio and data
are the same so unity gain is produced. The output
signal is fed to the TCXO where it frequency modulates the transmit signal.
5.11.9 TRANSMIT AUDIO
PTT switch (Q101/Q102) provides local microphone Push-To-Talk (PTT) indication to U105. U105
then tells U111 via the data bus that the local microphone PTT has been activated.
5.11.10 TRANSMIT AUDIO PROCESSING
Transmit voice from the backplane comes into the
MAC on P100, pin 32. When used this signal passes to
the transmit voice amplifier U130A. The output level
of the amplifier is adjusted by a level control. The
output of U130A is applied to another transmit voice
amplifier U130B and Transmit Voice Gate U158A.
U158A is controlled by A/D processor U111/latch
U107. When enabled, the gate passes the voice to
Transmit Option Gate U158C and on to the transmit
U164A amplifies the microphone audio signal to
provide the correct input level to U164B. Local Microphone Mute Gate U117C is controlled by A/D
processor U111/latch 106. The function of U117C is to
mute the local microphone audio when the local
microphone PTT switch is pressed. This prevents
interference if the microphone remains live when the
PTT switch is pressed.

The repeater on the lowest frequency channel in
each system must periodically transmit the station call
letters as a continuous-wave identification encoded by
Morse Code. This identification is programmed with
the Edit Parameters software.
5.11.11 TRANSMIT DATA AND CWID
PROCESSING
The data signal is produced by A/D processor
U111 on Transmit Data and Transmit Shape outputs.
The transmit shape output is normally the opposite
logic level of the transmit data output when data is
transmitted. However, the bit before a logic transition
occurs, the transmit shape output is the same logic
level as the transmit data output. This results in a logic
1 level that is slightly higher and a logic 0 that is
slightly lower. This pulse shaping minimizes interference between data bits when the data is filtered by the
low-pass filter.
The CWID output is controlled by A/D processor
U111/latch U107. This output is fed to CWID tone
generator U100B/A and turns the tone generator on
and off to create the Morse Code. From the tone
generator the signal is fed to bandpass filter U129A.
This filter passes the 800 Hz fundamental present in
the signal. The output of the filter is jumpered by P106
on J106, pins 2/3 and P107 on J106, pins 4/5 to the
summing amplifier and applied to gate U118D, and to
the modulation input of the Exciter.
The input and output connectors for the MAC are
defined as follows.
The data from U111 is fed to buffer U126A and
Transmit Data Enable Gate U117B. Gate U117B is
controlled by A/D processor U111 directly. When
enabled this gate passes the data to EEPOT U151.
U151 is an electronically adjustable potentiometer that
adjusts the gain of transmit audio amplifier U126B.
The gain of U126B can only be adjusted through the
software. Therefore, a computer must be attached to
the MAC card. U126B provides the required signal
level at the output of the low-pass filter. A relatively
stable DC bias voltage for U126C/D is required
because these stages are DC coupled to the transmit
TCXO (see Section 5.2.2) and changes in bias voltage
can cause fluctuations in the transmit frequency.
5.11.12 P101 SIGNALING CONNECTOR

connects the Address and Data buses and control lines
to the backplane connector. See Figures 5-18 and

This provides a path between the MPC main
processor and the processor and memory of the MAC.
This bus retrieves information programmed into

U126C/D form a low-pass filter that attenuates
square-wave harmonics in the data signal above
150 Hz to prevent interference with the audio band.
From this filter the signal is fed to summing amplifier
U129B and combined with the transmit audio signal.
The output of U129B is fed to Transmit Modulation
Mute Gate U118D. This gate is controlled by A/D
processor U111/latch U106. When enabled, transmit
audio and data are passed to the Exciter modulation
input and the transmit TCXO.

5.11.14 J100 A D LEVEL TEST POINT
5.12 INTERFACE ALARM CARD
This test point located on the front card edge is
used during alignment to monitor audio and data.
This card utilizes the information required to
operate the alarms designated in the programming of
the repeater. Data is received on the address bus from
the MPC for the; operation to perform, the processor
and external memory, open and close relays on the
outputs, and receive alarm indications on the inputs.
This information is either routed to external devices or
alarm outputs can be wired to alarm inputs (see
Section 3.3.3).

combination speaker/microphone is used during setup
and testing of the repeater.
The Interface Alarm Card (IAC) contains 4-input
contacts and 4-output contacts. The 4- inputs can be
disabled, energized or de-energized. The 4-output
relays are dry contacts that have a 2A rating and can
be either normally open or normally closed.

CIRCUIT DESCRIPTION
The electromechanical relay outputs are
comprised of eight SPDT (normally open) relays. The
relays are all open at power-on. Data to the relay is
latched by a write to the base address.
The IAC activates relays when alarm trigger
events occur. The IAC monitors for alarm activity in
the system and can set the various output relays as
defined by the user during programming. When an
external alarm is set it can be monitored from a remote
location. Refer to Section 3.3.3 for alarm programming information.
Figure 5-14 4 I/O J2 Alarm Outputs
Standard 12V/24V AC control transformer
outputs can be accepted as well as DC voltages. This
input voltage range is 5-24V RMS. External resistors
connected in series may be used to extend the input
voltage range.
5.12.1 RELAY OUTPUTS
The alarm relay outputs are provided via a
terminal block on the back of the repeater (see Figures
5-13 and 5-14).

5.12.2 ISOLATED INPUTS
Figure 5-15 S500-S503
The isolated alarm inputs are provided via a
terminal block on the back of the repeater (see Figures
5-13 and 5-14).
5.12.3 ALARM INDICATORS
There are three forms of alarm indicators from
the repeater. One form is the two red LEDs and display
combination on the MPC. Refer to Table 1-2 for the
combinations and definitions of the active alarms.
The isolated inputs are driven by either AC or DC
signals. The active high inputs can be set by switches
to be polarity sensitive, non-polarity sensitive or add a
resistance in series to dissipate unused power (see
Figure 5-15).
Another form is the output relay to the terminal
blocks at the rear of the repeater where outputs can be
wired to external devices or to alarm inputs.

required to provide an active alarm.
The alarms can be configured in various modes to
alert the system owner to conditions and hazards with
the equipment and the repeater site facility. A few
possibilities are shown in Figure 5-16. In this example:

Input Alarm 2 of Repeater 1 is connected to the door
of the building
Input Alarm 3 of Repeater 5 is connected to the fire
alarm system
AC fail alarm (#16 see Table 1-2) is mapped to
Alarm 2 Output so it can be transmitted (see Section
3.3.3)
Output Alarm 1 of Repeater 1 is connected to the
Input Alarm 1 of Repeater 2 and so on until Output
Alarm 1 is fed back to the Input Alarm 1 of
Repeater 1.
Then RF Shutdown alarm (#32) is mapped for
Alarm 1 in each repeater.
There are 40 internal alarms that can be included
in the output alarm configuration (see Table 1-2).
These alarms can also be programmed to send an
output as shown in the cross reference screen of the
alarm configuration menu (see Section 3.3.3). Among
these alarms are the thermal sense from the PA and the
AC fail alarm output on the terminal block at the rear
of the repeater to activate the battery backup.
5.12.5 P500 SIGNALING CONNECTOR
The input and output connectors for the IAC are
defined as follows. The signal interface connector
P500 (64 pin) connects the Address and Data buses
and control lines to the backplane connector. See
Figure 5-20.
This configuration allows Repeater 2 to give an
alarm when Repeater 1 has an RF Shutdown alarm
output, etc.
Pins 1-4
Pins 33-36
The input alarms are given a 15-character
description during programming and a Transmit ID.
These are used when an input alarm is activated to
send a Morse code message consisting of the description over the air to a monitoring transceiver
programmed with this ID.
ADDRESS BUS (A12-A19 Only)
This address bus provides a path between the
MPC main processor and the latches and multiplexers
of the IAC. This bus retrieves information
programmed into the MPC memory for the operation
of the IAC.

SECTION 6 ALIGNMENT AND TEST PROCEDURE
6.1 PRELIMINARY
The receiver alignment points diagram is shown
in Figure 6-1, and the receiver test setup diagram is
shown in Figure 6-2. Select the “TEST” menu and
then “RECEIVER” using the repeater programming
software.
6.1.1 GENERAL
The information which follows describes how to
tune and test the repeater. The Receiver, Exciter, and
PA sections which follow (6.2 - 6.5) describe how to
completely retune and test the RF stages of those
assemblies. If repairs are done so that retuning of an
assembly is required, perform the applicable procedure.
6.2.1 PRETEST
1. Preset L201, L203, L204, L206, L223 and L224
tuning screws about 1/4 inch above the top of the
casting.
The Full Repeater Alignment described in
Section 6.6 sets such things as various audio and data
levels, transmit power output, and TCXO frequencies. It does not tune the RF stages which must be
done using the individual assembly procedure just
described.
2. Preset L202 and L205 tuning screws just barely
above the tightening lock nuts.
6.2.2 VOLTAGE MEASUREMENTS
Apply power to the Receiver by plugging the 20pin cable from the RF Interface Board into J201 (see
Figure 6-1).
6.1.2 TEST SETUP
To tune individual RF assemblies, the RF unit
usually must be operated while it is removed from the
repeater. This requires extender power and control
cables. In addition, when adjustments are made on the
cards in the card rack, an extender card is usually
required to access the adjustments and test points.
These extender cables and cards and other test cables
are included in the 2000 Series Service Kit, Part
No.250-2000-230. Extender Cable Kit, Part No. 2502000-010, includes just the RF unit extender cables.
Measure the voltages at the following pins.
U206, pin 1
U207, pin 1
U208, pin 1
R309/R310 junction
+12V DC ±0.4V
+12V DC ±0.4V
+6V DC ±0.2V
+3.5V DC ±0.1V
6.2.3 PROGRAM TUNE-UP CHANNEL
1. Using the programming software, program the
Synthesizer for the desired receive channel number.
Use the Program Channel and not the FCC Channel
from Appendix A.
6.1.3 TESTING SOFTWARE
The software used to tune and test the repeater is
the same software used to program the repeater. This
software is described in detail in Section 3. The particular menus used are Test (see Section 3.6) and
Edit > Setup Parameters (see Section 3.3.1).
NOTE: The Channel Number, Channel Frequency and
Synthesizer Frequency appear at the bottom of the
screen.
2. Tune VCO helical L220 for +4.5V DC ±0.05V at
U209, pin 6 or TP2.
6.2 RECEIVER ALIGNMENT
CRITICAL ADJUSTMENT
3. Alternately tune L223 and L224 in 1/2-turn to 1turn increments until a voltage is measured on J201,
pin 13. At that time, tune L223 for a peak, then L224
for a peak.
The TCXO must be adjusted within 5 minutes of turning the AC power on to the repeater. Do not under any
circumstances try to set frequency later in any other
tests, as TCXO frequency stability then cannot be
guaranteed.
4. Retune L223/L224 for a peak at J201, pin 13.

voltage readings.
1. Place a pick-up loop (sniffer) or RF probe connected
to a frequency counter near L210.
8. The software programs the synthesizer is for the
receive channel.
2. Set Y201 (TCXO) for the Injection Frequency ±50
Hz (Inj Freq = chnl freq – 52.95 MHz).
6.2.6 FRONT END ADJUSTMENTS
6.2.5 VCO TEST
1. Set the signal generator to the Receive Channel at a
level sufficient to produce an output voltage on
J201, pin 7 (RSSI Output).
1. The software programs the synthesizer for 3 MHz
above the receive channel.
2. Tune L204, L205, L206, L201, L202, L203 and
L204 for a peak voltage on J201, pin 7. Decrease the
generator output level to maintain a 2-3V reading at
J201, pin 7.
2. The voltage on TP2 should be < 7.5V.
3. Record the voltage on J201, pin 13 __________.
5. The voltage on TP2 should be > 2V.
3. Set the generator for 100 µV into the receiver with a
1 kHz tone at ±3 kHz deviation
(1000 µV at the generator with 20 dB pad gives 100
µV at the receive antenna).
6. Record the voltage on J201, pin 13 __________.
4. Tune Z213 for 2V ±0.05V on TP4.
4. The software programs the synthesizer for
3 MHz below the receive channel.

The adjustments in Section 6.4.2 provide for
proper matching for the output of Q501 and set a
protective limit on the drive to the final transistors.
This limit is approached only under certain unusual
operating or repair conditions. However, improper
adjustment may impair normal operation of the PA,
especially at temperature extremes.
10.Set R425 for “best” square wave as observed on the
modulation analyzer output to the oscilloscope.
NOTE: Ensure that the oscilloscope is “DC” coupled
and the Modulation Analyzer has the 3 kHz LPF
switch set but NOT the 300 Hz HPF and 50 Hz HPF
switches set.
If Q501 or U501 are replaced, only Section 6.4.2
adjustments should be performed. No other adjustments are necessary in this case. Replacement of RF
components surrounding Q501/U501 does not justify
performing Section 6.4.2 adjustments. Replacement of
active components within the power control circuitry
of the RF Interface Board would require Section 6.4.2
adjustments.
12.Connect a 10 dB pad and modulation analyzer to
J402.
13.Press the “FM” and 3 kHz LPF switches of the
modulation analyzer.
16.Press the spacebar to key the Exciter.
These adjustments are necessary only if repairs
are made and such repairs are likely to affect the sensitivity/calibration of the forward or reverse power
detectors (e.g. replacement of detector diodes CR651/
CR652 or of the entire forward/reverse power detector
assembly). Replacement of components within the
power control circuitry of the RF Interface Board are
unlikely to affect the calibration of the power control.
17.Set R446 for ±3 kHz deviation (very little adjustment should be needed).
NOTE: Replacement of Q501, Q502, Q503 or U501
does not require the adjustments in this section.
14.Inject a 1 kHz sine wave with a level of 400 mV
RMS into P100, pin 32.
15.Adjust U149 for 707 mV RMS on P100, pin 29.
This waveform should be a clean sine wave.
18.Press the spacebar to unkey the Exciter.

SERVICING
SECTION 7 SERVICING
7.1 INTRODUCTION
7.2 SYNTHESIZER SERVICING
7.1.1 PERIODIC CHECKS
7.2.1 INTRODUCTION
This repeater should be put on a regular maintenance schedule and an accurate performance record
maintained. Important checks are receiver sensitivity
and transmitter frequency, modulation, and power
output. It is recommended that repeater performance
be checked regularly even though periodic checks are
not specifically required by the FCC.
Synthesizer malfunctions can be caused by no
VCO output, or the VCO is unlocked. The VCO can
be unlocked due to a bad synthesizer chip, an incomplete synthesizer phase-lock loop, or because the
synthesizer chip is programmed incorrectly.
To make certain that the synthesizer chip is
receiving programming data, pins 17, 18 and 19 of the
chip should be monitored during programming. Pin 17
(Enable) will go from a high to a low level. Pin 18
(Clock) will go from low to high in narrow pulses. Pin
19 (Data) goes from high to low with wider data
pulses.
7.1.2 SURFACE-MOUNTED COMPONENTS
A large number of the components used in this
repeater are the surface-mounted type. Since these
components are relatively small in size and are
soldered directly to the PC board, care must be used
when they are replaced to prevent damage to the
component or PC board. Surface-mounted components should not be reused since they may be damaged
by the unsoldering process. For more information on
replacing surface-mounted components, refer to the
Surface-Mounted Device Handbook, Part No. 0010576-002.
When the VCO is locked, the lock detect line of
the synthesizer pin 2 is high with very narrow negative-going pulses. These pulses become wider when
the VCO is out of lock. When this unlock condition
exists either in the Exciter VCO or the Receiver VCO,
it is relayed by the RF Interface board and is detected
by the MPC via the RF Data lines. The MPC then
does not allow the transmitter to key and the receiver
cannot unsquelch.
7.1.3 SCHEMATIC DIAGRAMS AND
COMPONENT LAYOUTS
When the VCO is unlocked, the fR and fV inputs
to the phase detector are not in phase (refer to Sections
5.1.12 and 5.2.5). The phase detector in the synthesizer then causes the VCO control voltage to go to the
high or low end of its operating range (0 or 9V). This
in turn causes the VCO to oscillate at the high or low
end of its frequency range.
Schematic diagrams and component layouts of
the PC boards used in this repeater are located in
Section 9. A component locator guide is also provided
for both the schematic and board layouts to aid in
component location.
7.1.4 REPLACEMENT PARTS LIST
As shown in Figures 5-1 and 5-4, a loop is
formed by the VCO, buffer, frequency input (FIN) and
the phase detector output (PD OUT). Therefore, if any
of these components begin to malfunction, improper
signals appear throughout the loop. However, correct
operation of the counters can still be verified by
measuring the input and output frequencies to check
the divide number.
A replacement parts list containing all the parts
used in this repeater is located in Section 8. Parts are
listed alpha numerically according to designator. For
information on ordering parts, refer to Section 1.9.
7.1.5 TCXO MODULES NOT SERVICEABLE
Transmit or Receive TCXOs are not field
serviceable because if a part is changed, a factory
recalibration must be performed to ensure that it stays
within its ±1 PPM tolerance.
Proceed as follows to check the input and output
signal of the synthesizer modules to determine if they
are operating properly.

7.2.2 TCXO MODULE
Modulus Control Signal
Check the signal at TCXO, pin 5. It should be
17.5 MHz for Y201 and Y401 at a level of approximately 3V P-P. If the TCXO is defective, it is not
serviceable and must be replaced with a new unit as
described in Section 7.1.5.
1. The frequency of the modulus control signal on
TEST 1, pin 9 should be equal to the N counter
output frequency (either in or out of lock). When the
VCO is in lock, this frequency should be 12.5 kHz.
2. The duty cycle of the modulus control signal determines the divide number of the prescaler. The duty
cycle (T1 ÷ T2) should be as follows:
Measure the signal at pin 20 (Ref In) of the
synthesizer chip. It will be approximately 1V P-P. If
the signal is low here, the TCXO buffer circuit may be
defective.
T1 ÷ T2 = A Cntr Div No ÷ N Cntr Div No
T2 = 80 µs when locked.
7.2.3 VOLTAGE CONTROLLED OSCILLATOR
(VCO)
Check for VCO output signal with a high impedance RF voltmeter. If there is no output signal, or if the
frequency is greatly off, the VCO is defective.
0V
Next, monitor the signal level at pin 11 (F In) of
the synthesizer chip. If the signal is less than
100 mV P-P, the VCO buffer is defective.

Lock Detector
Figure 7-2 Modulus Control Waveform
When the VCO is locked on frequency, the waveform at pin 2 (Lock Det) should be as follows. When
the VCO is unlocked, the negative-going pulses
should be much wider than those shown in Figure 7-1.
If the lock detect circuit is operating properly, check
prescaler input pin 11 (F In).
If the modulus control signal is not correct, the
synthesizer may be defective or the logic may not be
programming the correct divide number.
7.2.4 INTERNAL PRESCALER
The operation of the N and A counters can be
observed by monitoring pins 16 and 19. Pin 16 (fV)
equals fin ÷ (64N+A) = 12.5 kHz if the synthesizer is
locked. Pin 9 is the modulus control signal.
Checking Prescaler Divide Number
The prescaler divide number can be checked by
measuring the input and output frequencies. The prescaler divide number can be calculated as follows. (A
and N counter divide numbers are calculated as
described in Section 7.2.5.)
Prescaler Divide Number =
64 + (A Cntr Div No ÷ N Cntr Div No)
0V
Example: Channel 300 (receive)

Prescaler Div No = 64 + (45 ÷ 950) = 64.0474

SERVICING
Measure the prescaler input frequency at fin, pin
11. Then measure the output frequency at TEST 2, pin
13 and calculate the divide number. If the VCO is not
locked on frequency, the divide number should still be
correct. The measured frequencies may not be exactly
as calculated due to counter accuracy and resolution
limitations.
Example: Channel 300 (transmit)
NOTE: The counter should be connected to a high
stability reference oscillator.
To isolate a receiver problem to a defective
section, start by checking the DC voltages shown in
Section 5.5.6 and on the schematic diagram (Section
9). If that does not indicate the problem, perform the
performance tests in Section 6.2 to isolate the problem.
If the synthesizer is out of lock, the receiver is also
nonfunctional because the first injection and IF signals
will be incorrect.

7.2.5 CALCULATING “N” AND “A” COUNTER
DIVIDE NUMBERS
To isolate a transmitter problem to a defective
section, start by checking the DC voltages shown in
Sections 5.5.4 and 5.5.5 and on the schematic diagram
(Section 9). If that does not indicate the problem,
perform the performance tests in Sections 6.3, 6.4 and
6.5 to isolate the problem. If the synthesizer is out of
lock, the exciter is also nonfunctional because the software will not allow the repeater to transmit.

The power supply is a switch mode type with
very high voltages. It is highly recommended that the
power supply be returned to the factory for servicing
(see Section 1.8). A parts list, schematic and component layout are provided for those customers that
desire to do their own repairs (see Sections 8 and 9).
